Parts of a Wave

Front

What is the amplitude of a wave?

Back

The amplitude is the maximum distance a point on the wave moves from its rest position. It is related to the energy of the wave; higher amplitude means more energy.

Front

What is the wavelength of a wave?

Back

The 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, representing the maximum displacement of the wave from its rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.

Front

How does frequency relate to wave energy?

Back

Higher frequency waves carry more energy than lower frequency waves. This is because energy is directly proportional to frequency.

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 happens to sound waves as amplitude increases?

Back

As the amplitude of sound waves increases, the sound becomes louder. Amplitude is related to the intensity of the sound.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel through, while electromagnetic waves can travel through a vacuum.

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, such as sound waves.
