Mechanical waves, part 2

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

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, which relates to the energy and intensity of the wave.

Front

How does amplitude affect sound?

Back

Higher amplitude results in louder sounds, while lower amplitude results in quieter sounds.

Front

What is frequency in wave terminology?

Back

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

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch, while lower frequency corresponds to a lower pitch.

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 the speed of a wave?

Back

The speed of a wave is determined by the medium through which it travels and is calculated as speed = frequency × wavelength.

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.
