When you measure the amplitude, you are measuring distance from crest to resting point of the medium. What is this showing?

• Energy of the wave. Higher the amplitude, the greater the energy

• Energy of the wave. The lower the amplitude, the greater the energy

• The frequency

The wavelength shows...

• The length of a single wave within a train (from crest to crest)

• The length of a wave train

The higher the frequency of a wave train...

• The more waves there are in a given amount of time

• The less waves there are in a given amount of time

In order to calculate speed of a wave that is traveling, you multiply...

• wavelength x frequency

• frequency x amplitude

• amplitude x wavelength

What is the relation between the frequency of electromagnetic waves and their wavelength?

• Higher frequency= Higher wavelength

• Higher frequency= Lower wavelength

• Lower frequency = Lower wavelength

How do we know that light does not need a medium in which to travel?

• I can see light from the bulb in the ceiling.

• I can see light that travels through outer space from the sun.

• When I hold up a piece of paper to a lit flashlight, I can still see the light.
