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

Answers

Answer 1
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.

How does the presence of a large industry, like the automobile industry, influence/impact a city?

Answers

Answer:

The automobile gave people more personal freedom and access to jobs and services. It led to development of better roads and transportation. Industries and new jobs developed to supply the demand for automobile parts and fuel. These included petroleum and gasoline, rubber, and then plastics.

Explanation:

Large industries, such as the automobile industry provide job opportunities for civilians, so cities and towns may form around factories where products are needing to be produced. They also give civilians more of an advantage for migration and travel, allowing people to move more easily from place to place and discover and develop new cities and societies

Answers

The factory can affect the carbon cycle by releasing carbon dioxide into the atmosphere because it can trap heat from the sun in the atmosphere.

What is the Carbon cycle?

The carbon cycle is a term used to refer to the cycle of the chemical element Carbon in which it interacts in two ways with living organisms and the environment.

How does the carbon cycle work?

In general, the carbon cycle works in the following way:

Carbon is in the air mostly as carbon dioxide CO2 gas, which dissolves in water and reacts with water molecules to produce bicarbonate: HCO3

Photosynthesis carried out by land plants, bacteria and algae converts carbon dioxide or bicarbonate into organic molecules.

Organic molecules produced by photosynthesizing organisms pass through food chains, and cellular respiration converts organic carbon back to carbon dioxide gas.

Therefore, when a factory produces carbon dioxide, it is affecting the carbon cycle because it is releasing carbon molecules into the air that will unbalance the entire cycle.

Additionally, carbon, being a greenhouse gas, will trap the sun's heat in the atmosphere, causing an increase in the Earth's temperature.
