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

Top point of a transverse wave above the resting point of the medium is called a _________________.

• Crest

• Crust

• Trough

The bottom part of a transverse wave below the resting point is called a _________________________.

• Crest

• Crust

• Trough

The compressed part of a longitudinal wave is called a ______________________.

• Rarefaction

• Compression

• Transverse

The spread out part of a longitudinal wave is called a ________________.

• Rarefaction

• Compression

• Space

• Transverse

How many waves go past a point in one second. Measured in hertz (Hz).

• Frequency

• Speed

• Amplitude

• Wavelength

A wave that requires a medium to travel.

• Mechanical

• Electromagnetic

A wave that does not require a medium to travel, for example, it can travel through a vacuum.
