doppler effect

Front

What is the Doppler Effect?

Back

A change in frequency due to the relative motion of a wave source and an observer.

Front

True or False: The Doppler effect occurs when an observer moves towards a wave-making source.

Back

True

Front

Front

What happens to the pitch of sound waves as the source moves towards an observer?

Back

The pitch appears higher.

Front

What happens to the pitch of sound waves as the source moves away from an observer?

Back

The pitch appears lower.

Front

Short sound waves are associated with which type of pitch?

Back

High pitched.

Front

Long sound waves are associated with which type of pitch?

Back

Low pitched.

Front

What is the relationship between wave frequency and pitch?

Back

Higher frequency results in higher pitch, while lower frequency results in lower pitch.

Front

What is an example of the Doppler effect in everyday life?

Back

The changing sound of a passing siren from an ambulance.

Front

What is the effect of speed on the Doppler effect?

Back

The faster the source moves, the more pronounced the change in frequency.
