Waves and Electromagnetic Waves

How are waves produced?

vibrations

What are transverse waves?

Waves are produced by vibrations that are perpendicular to the direction of wave motion.

What are longitudinal waves?

Waves are produced by vibrations that are parallel to the direction of wave travel.

Give an example of transverse waves.

water waves

Give an example of longitudinal waves.

sound waves

What is the frequency of a wave?

number of waves per second

What is the period of a wave?

The time taken for one complete wave to pass a point.

What is the amplitude of a wave?

The maximum displacement of a point on the wave from its undisturbed position

What is the wavelength of a wave?

The distance from one crest to the next crest, or from one trough to the next trough

What is the wave equation?

velocity = frequency x wavelength

What is the wavefront of a wave?

An imaginary line that joins similar points in adjacent waves.
