Light and Sound Waves

Front

What happens to the pitch of a sound wave if the wavelength increases?

Back

The pitch of the sound wave decreases, resulting in a lower pitch.

Front

Which color of visible light has the shortest wavelength?

Back

Violet has the shortest wavelength among visible light colors.

Front

What is a translucent object?

Back

A translucent object allows some light to pass through but not enough to see clearly through it.

Front

True or false: The angle of incidence equals the angle of reflection.

Back

True.

Front

What is the distance from the line of origin to the top of a wave called?

Back

Amplitude.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels in a given amount of time.

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What is reflection in terms of light waves?

Back

Reflection is the bouncing back of light waves when they hit a surface.
