Properties of Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the definition of wavelength?

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

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 amplitude?

Back

Amplitude is the maximum height of a wave from its rest position, representing the wave's energy.

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 does frequency affect wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed = frequency × wavelength.

Front

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

Back

The energy of the wave increases as its amplitude increases.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.
