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 requires a medium to propagate.

Front

What is a transverse wave?

Back

A transverse wave is a type of mechanical wave where the particles of the medium move perpendicularly to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of mechanical wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

How do you calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Frequency x Wavelength.

Front

If a wave has a frequency of 50 Hz and a wavelength of 10 m, what is its speed?

Back

The speed of the wave is 500 m/s.

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?

Back

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

Front

What is amplitude?

Back

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