What is the electromagnetic spectrum?

Back

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

Front

Which type of electromagnetic waves have the shortest wavelength?

Back

X-rays have shorter wavelengths than visible light.

Front

What are gamma rays known for?

Back

Gamma rays have the highest energy in the electromagnetic spectrum and are the most dangerous type of radiation.

Front

What color of visible light has the shortest wavelength?

Back

Violet light has the shortest wavelength in the visible spectrum.

Front

What happens to light when it is reflected?

Back

When light is reflected, it bounces off a surface instead of being absorbed or transmitted.

Front

How do sound waves and light waves differ in speed?

Back

Light waves travel faster than sound waves.

Front

What is the relationship between wavelength and energy in electromagnetic waves?

Back

Shorter wavelengths correspond to higher energy, while longer wavelengths correspond to lower energy.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 400 nm (violet) to 700 nm (red).

Front

What is refraction?

Back

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

Front

What are radio waves used for?

Back

Radio waves are used for communication, including television, radio broadcasts, and mobile phones.
