Properties of Waves

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a wave move from their rest position. It is often represented as the height of the wave from the rest position to the crest.

What is a trough in a wave?

Back

A trough is the lowest point of a wave, where the wave dips below the rest position.

Front

What is wavelength?

Back

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

What is compression in a longitudinal wave?

Back

Compression is the part of a longitudinal wave where the particles are packed closely together.

Front

What is rarefaction in a longitudinal wave?

Back

Rarefaction is the part of a longitudinal wave where the particles are spread apart.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as the frequency of a wave increases, its wavelength decreases.

What is the definition of frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

What is a crest in a wave?

Back

A crest is the highest point of a wave, where the wave reaches its maximum height.

Front

How do you calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Wavelength x Frequency.

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through (like sound waves), while electromagnetic waves can travel through a vacuum (like light waves).
