Explanation:
Detailed explanation-1: -If the object is moving toward you, the waves are compressed, so their wavelength is shorter. The lines are shifted to shorter (bluer) wavelengths—this is called a blueshift.
Detailed explanation-2: -This effect is called the doppler shift. If the object is coming toward you, the light is shifted toward shorter wavelengths, blue shifted . If the object is going away from you, the light is shifted toward longer wavelengths, red shifted . The amount of shift is bigger if the emitting object is moving faster.
