Electromagnetic waves are different from mechanical waves because:

• Electromagnetic waves does not requieres a medium to travel

• Electromagnetic waves only travel through a medium

• Electromagnetic waves travel slower than mechanical waves

• Eectromagnetic waves are not emitted from the Sun

Longitudinal waves are...

• Move up and down and perpendicular

• Move back and forth and parallel

• Use both transfering the energy

Frequency of a wave is measured in units called

• Joules (J)

• Newtons (N)

• Hertz (Hz)

• Seconds
