Waves + Lights

Which waves have the most energy?

• low frequency, small amplitude

• high frequency, small amplitude

• low frequency, large amplitude

• high frequency, large amplitude

What is a vacuum? 

• A space with only air in it
• A space with NO matter at all present
• A machine you use to do your chores

Frequency is a measure of...

• length of the wave
• height of the wave
• number of waves a second
• number of waves an hour

When the wavelength increases the frequency will

• increase
• decrease

EM waves  

• Must travel through a vacuum
• Can travel through a medium or a vacuum
• Are the same type of wave as mechanical waves
• Can only travel through a vacuum

EM waves have the same speed but different:

• frequency & medium 
• wavelength & frequency
• medium & wavelength
• color & medium

7 is 

• Radio
• UV
• Infrared
• Gamma

4 is 

• radio
• UV 
• Visible Light
• X-ray

Which wave has the longest wavelength?

• A

• B

• C

• None (same wavelength)

Which wave has the highest frequency?

• A

• B

• C

• None (same frequency)
