Waves Review #2

Front

What is an echo?

Back

An echo is the sound that is reflected off a hard surface and heard again.

Front

What type of waves are sound waves?

Back

Sound waves are longitudinal waves.

Front

Why can't you hear sounds in outer space?

Back

You can't hear sounds in outer space because there is no medium (like air) for the sound waves to travel through.

Front

What is frequency?

Back

Frequency is the rate at which something repeats over time, measured in Hertz (Hz).

Front

Through which medium do sound waves travel the fastest?

Back

Sound waves travel the fastest through solids.

Front

What is amplitude?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

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

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is a compression in a longitudinal wave?

Back

A compression is a region in a longitudinal wave where the particles are closest together.
