Energy: Waves

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that a point on a wave moves from its rest position. It determines the loudness of a sound wave.

Front

What type of wave is characterized by particles moving parallel to the direction of wave travel?

Back

Longitudinal waves are characterized by particles moving parallel to the direction of wave travel.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's energy flow.

Front

What does the term 'wavelength' refer to in a wave?

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

How does frequency relate to wavelength?

Back

As frequency increases, the wavelength decreases, and vice versa, assuming the speed of the wave remains constant.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is the relationship between amplitude and sound intensity?

Back

Higher amplitude means greater sound intensity, resulting in a louder sound.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What happens to the energy of a wave as its amplitude increases?

Back

As the amplitude of a wave increases, the energy carried by the wave also increases.
