Mechanical Waves

Front

What is a mechanical wave?

Back

A mechanical wave is a disturbance that travels through a medium (solid, liquid, or gas) and transfers energy from one location to another.

Front

What are the two main types of mechanical waves?

Back

The two main types of mechanical waves are transverse waves and longitudinal waves.

Front

Define amplitude in the context of waves.

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

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 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 in relation to waves?

Back

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

Front

How is wave speed calculated?

Back

Wave speed is calculated using the formula: Wave Speed = Frequency x Wavelength.

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 a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement above the rest position.
