What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What is the difference between a crest and a trough in a wave?

Back

A crest is the highest point of a wave, while a trough is the lowest point.

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.

Front

How does sound travel through different mediums?

Back

Sound can travel through solids, liquids, and gases, as it requires a medium to propagate.

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 formula for wave speed?

Back

Wave speed (v) is calculated using the formula v = frequency (f) × wavelength (λ).

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particle displacement is parallel to the direction of wave propagation.

Front

What is the principle of superposition in waves?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.
