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 the formula to calculate the speed of a wave?

Back

Speed = Wavelength × Frequency.

Front

What is the speed of a wave with a wavelength of 10 mm and a frequency of 5.0 hertz?

Back

50 mm/s.

Front

In which medium does sound travel the fastest?

Back

Sound travels fastest in solids, specifically in cast iron.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves collide and the resulting wave has a smaller amplitude than the original waves.

Front

What type of wave is a sound wave?

Back

A sound wave is an example of a longitudinal wave.

Front

What is a 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 the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.
