The apparent wavelength of light from a star moving away from the earth is 0.02% more than the actual wave length. What is the velocity of star

The apparent wavelength of the light from a star, moving away from the earth is 0.01% more than its real wavelength. The speed of the star with respect to earth is

The apparent wavelength of the light from a star, moving away from the earth, is 0.01% more than its real wave length. The speed of the star with respect to the earth is ……………… .

A star emitting light of wavelength 6000 Å is moving towards the earth with a speed of 3 xx 10^(6) m//s . What is the apparent wavelength of the emitted light ?

A stream of protons are coming down vertically towards the earth. The earth's magnetic field is directed from geographic south to north The proton will be deflected

Astronomers have observed that light coming from far away starts do not show the same spectrum as observed on Earth. Each wavelength is shifted slightly towards the red end of the spectrum. It is observed that the 1^(st) line of Lyman series shows 121 nm on Earth, but from the star it shows 122nm. The speed of the star with respect to Earth is close to

What is the shape of the wavefront in each of the following cases ? The portion of the wavefront of light from a distant star intercepted by the earth .
