_____ waves NEED a medium to travel.

• Seismic

• Light

• Mechanical

the number of waves that pass a certain point.

• wave speed

• frequency

The wave shown in the diagram is an example of a(n)...

• transverse wave

• EMR wave

• longitudinal wave

• light

Which wave has more energy? Why?

• Top wave because the amplitude is smaller

• Bottom wave because the amplitude is larger

• They are the same because the wavelengths are equal
