EM Waves

Which wave has the largest wavelength?

• A

• B

• C

• None (same wavelength)

When the wavelength of a wave increases, the frequency will

• increase

• decrease

Which property determines the amount of energy for an ELECTROMAGNETIC wave?

• amplitude

• frequency

• particle size

• medium

Which property determines the amount of energy for a MECHANICAL wave?

• amplitude

• frequency

• particle size

• medium

All EM waves travel at  

• different speeds
• the speed of sound
• the speed of light
• the speed of a vacuum

How are EM waves different from Mechanical waves?

• EM waves need a medium, but mechanical waves don't

• Mechanical waves need a medium, but EM waves don't

• EM waves can travel through empty space only, but mechanical waves can travel through anything

• Mechanical waves transfer matter, but EM waves transfer energy

EM waves have the same speed but different

• frequency & medium 

• wavelength & frequency

• medium & wavelength

• color & medium

Which of these lists the EM waves from Highest to lowest frequency?

• Radio -  Micro - Gamma - Visible light - UV - Xrays - Infrared - Xrays
• Radio - Micro - Infrared - Visible light - UV - X - Gamma waves
• Gamma - Xray - UV - Visible light - Infrared - Micro - radio

Which of these waves has the longest wavelength?

• microwave

• radio

• gamma

• visible light

7 is 

• Radio
• UV
