To Describe:The relative motions of objects when light is redshifted and blueshifted in term Doppler Effect.

Explanation of Solution
Introduction:
When the direction of the waves is towards us, the apparent wavelength decreases a little.If it’s the waves of visible light, light colors may change significantly.When wavelength reduces, they change towards the blue end of the spectrum. Astronomers call this a blueshift.When the source moves away from us and the wavelength is longer, it’s a redshift of the light.
When analyzing a two-star system you can tell which one is moving towards you and which one is moving away by observing how the frequencies/wavelengths show variation using the Doppler effect. Doppler Effect equation can be used to calculate the radial velocity of an object.For this calculation, we have to know three parametersa) the
