Unit 2 Review

Front

What is the definition of Refraction?

Back

The bending of waves as they enter a new medium.

Front

What kind of wave is a transverse wave?

Back

A wave where the particle displacement is perpendicular to the direction of wave propagation.

Front

What is the unit of frequency?

Back

Hertz (Hz) is the unit of frequency.

Front

What property of a wave is represented by amplitude?

Back

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

Front

What happens when a wave bends as it passes through at an angle from one medium to another?

Back

This phenomenon is called refraction.

Front

What is a compressional wave?

Back

A wave where the particle displacement is parallel to the direction of wave propagation.

Front

What is the definition of wavelength?

Back

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

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 definition of amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position to its crest.

Front

What is reflection in terms of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier.
