S8P4 - Waves Review

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium. It determines the loudness of a sound wave.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

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

Front

What is pitch?

Back

Pitch is the perceived frequency of a sound; higher frequencies correspond to higher pitches.

Front

What is the relationship between amplitude and sound volume?

Back

Increasing the amplitude of a sound wave increases its volume.

Front

What does a wave carry or transmit?

Back

Waves carry or transmit energy.

Front

What is the difference between compression and rarefaction in a longitudinal wave?

Back

Compression is the region where particles are closest together, while rarefaction is the region where particles are furthest apart.

Front

How do electromagnetic waves differ from mechanical waves?

Back

Electromagnetic waves do not require a medium to travel through, while mechanical waves do.

Front

List electromagnetic waves in order from highest to lowest frequency.

Back

gamma, X-rays, UV, visible light, infrared, microwaves, radio waves.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).
