Explain Doppler effect in light. Distinguishbetween red shift and blue

1.	Explain Doppler effect in light. Distinguishbetween red shift and blue shift.(To explain Doppler Effect in light, read eitheror (i)or (ii) )
Answer» Light waves from a moving source experience the Doppler effect to result in either a red shift or blue shift in the light's frequency. This is in a fashion similar to other sorts of waves such as sound waves. The major difference is that light waves do not require a medium for travel Red light and Blue lights describe how light changes as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion. Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter.

Red light and Blue lights describe how light changes as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion.
