SC.8.E.5.11 - Electromagentic Spectrum

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, microwaves, infrared, ultraviolet, X-rays, and gamma rays.

What happens to light when it is reflected?

Back

When light is reflected, it bounces off a surface rather than being absorbed or transmitted through it.

Front

What is absorption in the context of electromagnetic waves?

Back

Absorption occurs when an atom or molecule takes in energy from electromagnetic waves, causing its electrons to move to higher energy levels.

Front

What is emission of light?

Back

Emission of light occurs when electrons in an atom return to lower energy levels, releasing energy in the form of light.

Front

Which type of electromagnetic waves has the highest energy?

Back

Gamma rays have the highest energy and are the most dangerous type of electromagnetic waves.

Front

What are ultraviolet (UV) rays?

Back

Ultraviolet rays are a type of electromagnetic radiation that can be harmful to living organisms and are found between visible light and X-rays in the electromagnetic spectrum.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

What is the difference between X-rays and gamma rays?

Back

X-rays are produced by high-energy processes involving electrons, while gamma rays are emitted from the nucleus of radioactive atoms.

Front

What is refraction?

Back

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

Front

What is the role of the ozone layer in relation to UV rays?

Back

The ozone layer absorbs a significant amount of the sun's harmful ultraviolet radiation, protecting living organisms on Earth.
