Sound and light waves

Front

What is a transverse wave?

Back

A wave where the disturbance is at a right angle to the direction the wave is moving. Example: Heat and light waves.

Front

What is sound?

Back

Vibrations that travel through the air or medium.

Front

What is wavelength?

Back

The distance between successive crests of a wave.

Front

In which medium do sound waves travel fastest?

Back

Sound waves travel fastest in solids.

Front

What is a longitudinal wave?

Back

Waves where the disturbance moves in the same direction as the wave. Example: Sound wave.

Front

What is frequency?

Back

The rate at which a vibration occurs, measured in Hertz (Hz).

Front

What is amplitude?

Back

The maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What is the relationship between frequency and wavelength?

Back

Higher frequency means shorter wavelength, and lower frequency means longer wavelength.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.

Front

What is reflection of sound?

Back

The bouncing back of sound waves when they hit a surface.
