Electromagnetic Spectrum

Which electromagnetic waves have the highest frequencies and the shortest wavelengths?

• microwaves
• visible light
• gamma rays

For waves in any medium, as the wavelength decreases, what happens to the frequency?

• It also decrease
• It stays the same
• It increases

Select the correct order of waves on the EMS 

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

Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma Rays
• Radio Waves
• Visible Light
• Infrared rays

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy

• Radio waves
• Ultraviolet Rays
• Gamma Rays
• X-rays
