Mechanical Waves

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases.

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Frequency × Wavelength.

Front

What is the speed of a sound wave with a frequency of 250 Hz and a wavelength of 8 m?

Back

2000 m/s.

Front

What do waves transfer?

Back

Energy.

Front

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

Back

500 m/s.

Front

What is the definition of a mechanical wave?

Back

A mechanical wave is a disturbance that travels through a medium, transferring energy from one point to another.

Front

What are the two main types of mechanical waves?

Back

Transverse waves and longitudinal waves.

Front

In a transverse wave, what direction do the particles of the medium move relative to the direction of the wave?

Back

Perpendicular.

Front

In a longitudinal wave, what direction do the particles of the medium move relative to the direction of the wave?

Back

Parallel.

Front

What is a wave's amplitude?

Back

The maximum displacement of a point on the wave from its rest position.
