electromagnetic spectrum

True or false: as you move along the spectrum, left to right, the wavelengths decrease in size (get smaller)

• true
• false

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

How are electromagnetic waves different from other waves? 

• They have very short wavelengths 
• They transmit energy instead of matter 
• They can travel through a vacuum 
• They can change direction by reflection
