S8P4 Waves Review 2

Front

What is a wave?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, 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 wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases and vice versa.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by wavelength or frequency.

Front

What is reflection?

Back

Reflection is the bouncing back of a wave when it hits a surface that it cannot pass through.

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 diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is absorption?

Back

Absorption is the process by which a wave's energy is taken up by a material, converting it to other forms of energy, such as heat.
