Waves

Front

What are electromagnetic waves?

Back

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

Front

What happens to particles in a medium after a wave passes through?

Back

Particles in the medium return to their original position after the wave passes.

Front

How do you determine a wave's frequency?

Back

Frequency is determined by counting the number of cycles in a given period of time.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another.

Front

What are compression and rarefaction in longitudinal waves?

Back

Compression is when particles are pushed together, and rarefaction is when they are pulled apart.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is amplitude?

Back

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

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels per unit of time.

Front

What is the relationship between frequency and wavelength?

Back

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