Select the correct order of waves on the EMS.

• Radio, Micro, Infrared, Visible, UV, X-ray, Gamma

• Gamma, X-ray, UV, Visible, Infrared, Radio, Micro

• Visible, Micro, Infrared, UV, X-ray, Gamma, Radio

• Micro, Radio, Visible, Infrared, UV, X-ray, Gamma

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

• Radio waves

• Ultraviolet rays

• Gamma rays

• X-rays

Which has the longest wavelength and, therefore, the lowest energy?
