What is the doppler effect?

• a change in the frequency of sound, light or other waves to cause a change in pitch

• A change in pitch that causes frequency, sound, light and other waves to disappear

• I have no idea

• A change in sound that alters frequency

when a noise is moving towards an observer, the closer it comes...

• the lower the pitch

• the longer the noise

• the higher the pitch

• the quieter the noise
