Properties of waves

Front

What is 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. It is related to the energy of the wave; higher amplitude means more energy.

Front

What does a wave carry from one place to another?

Back

A wave carries energy from one place to another, not matter or people.

Front

What is wavelength in a wave?

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

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 amplitude affect the energy of a wave?

Back

Higher amplitude means the wave has more energy, while lower amplitude means less energy.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What type of wave is a sound wave?

Back

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

Front

What type of wave is a light wave?

Back

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

Front

What is the formula for wave speed?

Back

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