Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium.

Front

What is the electromagnetic spectrum?

Back

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

Front

Which type of wave has the highest frequency in the electromagnetic spectrum?

Back

Gamma rays.

Front

What type of wave is sound?

Back

Sound is a mechanical wave.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What are UV rays?

Back

Ultraviolet (UV) rays are a type of electromagnetic radiation emitted by the sun, with wavelengths shorter than visible light.
