Parts of a Wave

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that a point on a wave moves from its rest position. It is a measure of the energy of the wave.

Front

What does frequency measure in a wave?

Back

Frequency measures the number of waves that pass a given point in one second, typically expressed in hertz (Hz).

Front

True or False: Waves with a greater amplitude have less energy than waves with a lower amplitude.

Back

False. Waves with a greater amplitude have more energy.

Front

What is wavelength in the context of waves?

Back

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

Front

Which color of light has the longest wavelength?

Back

Red light has the longest wavelength among visible light.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the period of a wave?

Back

The period is the time it takes for one complete wave to pass a given point, measured in seconds.

Front

What is a wave crest?

Back

A wave crest is the highest point of a wave, where the amplitude is at its maximum.

Front

What is a wave trough?

Back

A wave trough is the lowest point of a wave, opposite to the crest.

Front

How does energy relate to amplitude in waves?

Back

Higher amplitude waves carry more energy, while lower amplitude waves carry less energy.
