Waves Review

Front

What happens to the wavelength of a wave when its frequency increases at constant speed?

Back

The wavelength decreases.

Front

What creates mechanical waves?

Back

Mechanical waves are created when a source of energy causes a medium to vibrate.

Front

Why do we see lightning before we hear thunder?

Back

Light travels faster than sound.

Front

What are waves called that move the particles of the medium parallel to the direction of wave travel?

Back

Longitudinal Waves.

Front

What is the distance between two corresponding parts of a wave called?

Back

Wavelength.

Front

What is the relationship between frequency and wavelength in a wave?

Back

As frequency increases, wavelength decreases.

Front

What type of wave moves particles perpendicular to the direction of wave travel?

Back

Transverse Waves.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of a wave from its rest position.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels per unit of time.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.
