Waves Review

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are mechanical waves?

Back

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

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 refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another due to a change in speed.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What factors affect the speed of sound?

Back

The speed of sound is affected by the medium it travels through, temperature, and pressure.

Front

What is frequency?

Back

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

Front

What is wavelength?

Back

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

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from gamma rays to radio waves.

Front

What is the relationship between frequency and wavelength?

Back

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