Question

Doppler Effect acts on ___________ type of wave

● Review: Doppler Effect is the perceived change in ______ of a wave when the object emitting that wave is in ______
● This is a __________________________________ between light and sound – it happens to ___________!
● How we know the universe is _________________________ - the redshift

Answer 1

option c

Step-by-step explanation:

As per the doppler's effect, when an object in the universe move at a fast speed away from the observer, its possesses a high wavelength as compared to its original wavelength.

Since red light has the highest wavelength, any object's wavelength moving towards a high values is said to be red shifted.

As per the doppler's effect, when an object in the universe move at a fast speed away from the observer, its possesses a high wavelength as compared to its original wavelength.Since red light has the highest wavelength, any object's wavelength moving towards a high values is said to be red shifted.Thus, the higher the wavelength, the lower will be the frequency of an object and hence it moves at a faster speed away from the observer and hence the universe is said to be expanding.
