Front

What is scattering?

Back

Scattering is the process by which particles or waves are forced to deviate from a straight trajectory due to non-uniformities in the medium through which they pass.

Front

What happens to sound waves when they travel through denser substances?

Back

The speed of sound waves increases when they travel through denser substances.

Front

What happens to light waves when they travel through denser substances?

Back

The speed of light waves decreases when they travel through denser substances.

Front

What is reflection?

Back

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

Front

Which type of electromagnetic wave is the most harmful to humans?

Back

Gamma rays are the most harmful type of electromagnetic wave to humans.

Front

What is absorption in the context of waves?

Back

Absorption is the process by which a wave's energy is taken up by the medium it is traveling through, converting the wave energy into other forms of energy.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in its speed.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.
