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.
Explanation:
A waterfall is an area where water flows over a vertical drop or a series of steep drops in the course of a stream or river.
Answer:
Jupiter is the 5th and most fastest spinning planet it completes an orbit around 11.86 years every year.
Explanation:
Jupiter is the biggest planet in our solar system, it's a gaianet and gaseous planet about 2.5 tims of all the planets combined. Like other planets jupiter doesn't have any defined solid surface, as a result of its rotation it has an oblate spheroid bulge along the equator and at it's boundaries are greater turbulence of storms and popular amongst them is the great Red storm.A complete day at the equator can be estimated by just nine hours and 50 minutes at the poles.
C because a governmental isn’t going to want to lower the standard of living. It would make living harder and add more poverty.
