6th Grade Waves Review

Front

What are the units for frequency?

Back

Hertz (Hz) is the unit for frequency.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and their crests and troughs align, resulting in a wave of greater amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and their crests align with troughs, resulting in a wave of lesser amplitude.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What does amplitude represent in a wave?

Back

Amplitude is the maximum distance a wave moves from its rest position, indicating the wave's energy.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) can be calculated using the formula f = 1/T, where T is the period of the wave.

Front

What is the period of a wave?

Back

The period is the time it takes for one complete wave cycle to pass a given point.
