When blue shift occurs, how does the wavelength of light that we see change?

Answers

The doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the detector.
Doppler effect in light is actually a relativistic effect (caused due to relativistic time dilaton and can be explained by special theory of relativity) but somewhat similar to the one which happens in sound waves. This effect has nothing to do with the bending in spacetime.
When the source is moving away from the detector, the wavelength of the light emitted from the source appears to be increased as seen by the detector (think of a wave being stretched), as a result the frequency decreases (since, speed of light is constant in all frames). Due to this decrease in frequency the light emitted from the source appears more red (since red color is on low frequency side in the electromagnetic spectrum) compared to the situation when source was at rest.
Vice versa for the source moving towards the detector
This shift in frequency is also known as doppler shift.
The shift in frequency when the source is moving away is known as redshift and the opposite one is known as blueshift.

important of science and technology in nepal(essay)​

Answers

Answer:

Science and technology in Nepal, sometimes shortened to S&T in Nepal, encompass the development and challenges of scientific research and technological innovation in Nepal, and how these developments, in turn, affect Nepali society, politics, and culture. Science and technology are small but emerging fields in Nepal. The Ministry of Education, Science and Technology is the ap.ex government body tasked with the responsibility of overseeing the development of science and technology in the country.

An underdeveloped country, Nepal is plagued with problems like poverty, il.literacy, unemployment, and the like. Consequently, science and technology have invariably lagged behind in the priority list of the government. On the other hand, citing p.oor university education at home, tens of thousands Nepali students leave the country every year, with half of them never returning. These factors have been huge deterrents to the development of science and technology in Nepal.

Now that the cake has been cut into 10 equal slices, how much space is covered by icing on the top of each piece of cake? the cake has a diameter of 9 inches.

Answers

The space (area) covered by icing on the top of each piece of cake is 0.636 inches squared.

What is space?

Space refers to the surface or area of an object.

The space can also refer to the distance or volume covered in a measurement.

The area of space using its diameter can be computed using the following formula.

Data and Calculations:

Diameter of cake = 9 inches

Radius = 4.5 inches (9 inches/2)

The radius of each of the ten slices = 0.45 inches (4.5/10)

Area = πr^2

where π = 22/7

r = radius

Area (space covered by the icing on the top of each piece of cake

= 22/7 x 0.45^2

= 22/7 x 0.2025

= 0.636 inches squared.

Thus, the space (area) covered by icing on the top of each piece of cake is 0.636 inches.

Compare and contrast The Solar Nebula Hypothesis and The Big Bang theory.​

Answers

Answer:

The Nebular Hypothesis is an explanation for the formation of solar systems. The Big Bang Theory explains the origins of this universe.

Explanation:

Chalk and cheese.

COMPARISON:

1) there is no comparison as they refer to radically different things:

2) The nebular theory refers to the solar system.

The Big Bang refers to the universe as a whole.

CONTRAST:

To put the difference between the solar system and the universe in context, the solar system is measured in astronomical units (AU), the universe in billions of light years.

An AU is the distance between the sun ☀️ and earth . It takes light about 8 minutes to cover 1 AU.

A light year is the distance that light will travel in a year. So, there are about 63241 AUs in a light year.

To put that in context, Pluto (on average) is a mere 40 AUs from the sun.

The nearest star to the sun is Proxima Centauri that is 4.24 light years away. The centre of the Milky Way (our galaxy) is about 30,000 light years away. Andromeda, the nearest spiral galaxy to the Milky Way, is 2.5 MILLION light years away. The size of the observable universe is 93 BILLION light years. You get the drift.

So, the nebular theory refers to what amounts to a spec of sand on a beach when compared to what the Big Bang theory explains.

One of these put forward a new way of calculating the size of molecules. Another explained Brownian motion the random dance performed by specks of dust trapped in a fluid. Einstein suggested that the tiny particles making up the fluid its atoms or molecules were bouncing against the specks of dust and causing the motion. These papers helped to establish the reality of atoms and molecules. Another of Einsteins 1905 papers explained the photoelectric effect the way that metals could emit electrons (tiny charged particles) from their surface when light was shone on them. Most scientists believed that light travelled in waves like sound or water waves. But Einstein suggested that the photoelectric effect could be explained if light could also behave as a stream of tiny packets of energy.(2) Einsteins paper on the photoelectric effect helped give birth to quantum theory, and it was for this paper that Einstein received the Nobel Prize in 1922. Quantum theory led, in the 1920s and 1930s, to another revolution in physics. Physicists showed that, as well as light waves behaving like particles, particles could sometimes act as waves. This theory established objective probability in physics. This was the idea that completely unpredictable chance events can take place at the subatomic level. Einstein never fully accepted the prevalent interpretation of quantum theory. But, while many of these interpretations involve wild metaphysical flights of fancy, the physical results are, like those of relativity, very well established. (3) Marrying together the two pillars of 20th century physics relativity and quantum theory is a central problem for physics even today. Successfully doing this may require a revolution in science similar to those begun by Newton and Einstein. There are three main interconnected driving forces for such changes in science. The first is the development of technology. Changes in technology can make new experiments possible and they also influence the problems that scientists develop an interest in. Newton was fascinated by the new machines of the 17th century. Similarly, Einstein was fascinated by electricity and magnetism. This influence also works in a negative way. The governments and multinationals that control technology are often able to dictate what is researched. (4) The second factor driving scientific progress is the way that the dominant ideas in society change. Ideas from the broader culture can impinge upon science. Newtons ideas were part of a revolutionary new attempt at a rational explanation of both nature and society. On the other hand, the dominant ideas in society can also limit the development of science. This is most obvious in the social sciences, where delving too deeply into how society is organized might raise difficult questions for our rulers. Less is at stake in the natural sciences. Indeed, improvements in natural sciences are vital to our rulers if they want to compete effectively with each other. But the distorted worldview of capitalism still impacts on science. Extremely narrow and specialized bodies of knowledge developcreating problems for scientists trying to bring about the kind of sweeping revolution heralded by Einstein. (5) Finally, science moves forward because scientists seek to develop logically consistent theories. This can push them beyond the dominant or common sense ideas of their time. Einsteins breakthrough cannot be reduced simply to changes in technology or wider cultural and ideological shifts. Science is not simply the gathering and ordering of data about the outside world. It also requires abstractiondeveloping theories about the underlying laws of nature that are usually not immediately apparent. This crucial role of theory is not just a feature of the natural sciences. (6) Einstein argued that common sense is the prejudices acquired by age 18. Marxist theory, which is a social science topic, challenges common sense political ideas. If we, according to this theory, want to change the world, we need to combine our actions with theory that digs below the surface appearance of society to understand how the system works.What is the writers point of view?
