EMS 2

A wave with a large wavelength will have a ______ frequency and _____ energy

• high, low
• high, high
• low, high
• low, low

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

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
