EM waves

Frequency is a measure of...

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

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

Visible light is 

• radiation
• light
• a way to transfer energy
• all of these
