The Doppler effect applies to both sound and light waves.
The frequency of observed light is different from the emitted frequency when the source of light is moving relative to the observer.
A frequency shift in visible light can result in a change of color.
Longer wavelengths have lower frequencies and shorter wavelengths have higher frequencies.
Blue light has a shorter wavelength than red light.
Shifts towards longer wavelengths are called "redshifts" and shifts towards shorter wavelengths are called "blueshifts".
A shift in wavelength implies a shift in frequency.
When the source moves towards the observer, waves are blueshifted.
When the source moves away from the observer, waves are redshifted.
The same ideas that apply to the Doppler effect with sound can be applied to the Doppler effect with light.

Test your knowledge on the fascinating phenomenon known as the Doppler effect, which affects both sound and light waves. Learn about the frequency shift in light when the source is in motion, and how it can result in a change of color. Understand the relationship between wavelength and frequency, and the significance of redshifts and blueshifts in the Doppler effect. This quiz will cover all the essential concepts of the Doppler effect and its application to both sound and light waves.
