EM Spectrum and Light Flashcard

Front

What is the electromagnetic spectrum?

Back

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

What happens to light when it strikes a mirror?

Back

When light strikes a mirror, it is reflected, meaning it bounces back instead of being absorbed or refracted.

Front

Which electromagnetic waves have a shorter wavelength than visible light?

Back

X-rays have a shorter wavelength than visible light.

Front

What type of electromagnetic energy carries the least energy?

Back

Microwaves carry the least energy among the types of electromagnetic energy.

Front

What part of the electromagnetic spectrum causes sunburn?

Back

Ultraviolet radiation causes sunburn.

Front

Can light travel through empty space?

Back

Yes, light can travel through empty space as well as through matter (gas, liquid, solid).

Front

What is refraction?

Back

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

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, such as a mirror.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with long wavelengths, used for communication.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light, often associated with heat.
