Waves

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What is the crest of a wave?

Back

The crest of a wave is the highest point of the wave.

Front

What is frequency in the context of waves?

Back

Frequency is the number of wavelengths that pass a given point per second.

Front

Can mechanical waves travel through a vacuum? Why or why not?

Back

No, mechanical waves cannot travel through a vacuum because they require a medium to propagate.

Front

How is the frequency of a wave related to its wavelength?

Back

Frequency is inversely proportional to wavelength; as frequency increases, wavelength decreases.

Front

What is a wave's amplitude?

Back

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

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium and can travel through a vacuum.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed is equal to frequency multiplied by wavelength (v = f × λ).

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the particle displacement is parallel to the direction of wave propagation.
