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

What happens to the wavelength when the frequency is higher?

Back

The wavelength gets shorter.

Front

True or False: The Doppler effect is seen when a wave-making source moves toward an observer.

Back

True.

Front

The Doppler effect causes a shift in...

Back

All of the above (pitch, wavelength, frequency).

Front

All waves carry ______________.

Back

Energy.

Front

What is the relationship between frequency and wavelength in waves?

Back

As frequency increases, wavelength decreases.

Front

What happens to the pitch of a sound as the source moves closer to an observer?

Back

The pitch increases.

Front

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

Back

The pitch decreases.

Front

What is a practical example of the Doppler Effect?

Back

The changing sound of a passing siren from an ambulance.

Front

What type of waves does the Doppler Effect apply to?

Back

It applies to all types of waves, including sound and light.
