Electromagnetic Spectrum

How are electromagnetic waves different from other waves?

• They have very long wavelengths

• They can travel through empty space

• They transmit energy instead of matter

• They can change direction by reflection

Select the correct order of waves on the EMS from the longest wavelength to the shortest wavelength.

• Micro, Radio, Visible Light, Infra, Ultra, X-ray, Gamma

• Micro, Visible Light, Infra, Ultra, X-ray, Gamma, Radio

• Gamma, X-ray, Ultra, Vis, Infra, Micro, Radio

• Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma
