Front

What is the Doppler Effect?

Back

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

Back

The distance between two consecutive peaks of a wave.

Front

What is frequency?

Back

The number of waves that pass a point in one second.

Front

What is amplitude?

Back

The height of a wave from its rest position, indicating the energy of the wave.

Front

What is a sound wave?

Back

A type of wave that travels through air (or other mediums) and is perceived as sound.

Front

What is a transverse wave?

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave.
