Question

As you have learned, objects in space emit different wavelengths of electromagnetic radiation. Use the chart to match wavelengths to the correct region of the electromagnetic spectrum.

a) Gamma rays
b) Infrared
c) Radio waves
d) Ultraviolet

Answer 1

The different regions of the electromagnetic spectrum, in order of increasing wavelength, are: radio waves, infrared, visible light, ultraviolet, and gamma rays.

Step-by-step explanation:

The different regions of the electromagnetic spectrum, in order of increasing wavelength, are:

1. Radio waves: These have the longest wavelengths and are used for communication, such as radio and television.
2. Infrared: These have slightly shorter wavelengths than radio waves and are used for thermal imaging and remote controls.
3. Visible light: This is the range of wavelengths that our eyes can detect and is responsible for the colors we see.
4. Ultraviolet: These have shorter wavelengths than visible light and can cause sunburn and damage to the skin.
5. Gamma rays: These have the shortest wavelengths and are produced by nuclear reactions and radioactive decay.
