The effect for frequency/wavelength change when source moves towards/away is called?
A) Doppler Effect
B) Redshift
C) Cosmic Microwave Background
D) Gravitational Lensing
Answer Revealed Below!
The effect of frequency and wavelength change when a source moves towards or away from an observer is called the Doppler Effect. When the source approaches the observer, the wavelengths of the waves it emits become compressed, resulting in an increase in frequency known as blueshift. Conversely, when the source moves away, the wavelengths are stretched, leading to a decrease in frequency, referred to as redshift. This effect is observable in both sound waves, such as the changing pitch of a passing siren, and electromagnetic waves, such as the light from stars and galaxies. The Doppler Effect is crucial in various fields, including astronomy, where it helps determine the motion and velocity of celestial objects.
