# Topic 3-Waves

What are waves?
Waves are vibrations that transfer energy from place to place without matter being transferred. There are two types of waves, transverse and longitudinal.

What is a transverse wave? Name some examples
Light and other types of electromagnetic radiation are transverse waves. Water waves and S waves (a type of seismic wave) are also transverse waves. In transverse waves, the vibrations are at right angles to the direction of travel.

What is a longitudinal wave? Name some examples
Sound waves and waves in a stretched spring are longitudinal waves. P waves (relatively fast moving longitudinal seismic waves that travel through liquids and solids) are also longitudinal waves. In longitudinal waves, the vibrations are along the sa

What is the amplitude?
The maximum disturbance from it's undisturbed position.
4 of 7
What is the wavelength?
The distance between one point on one wave and the same point on the next wave.
5 of 7
What is the frequency?
The frequency of a wave is the number of waves produced by a source each second. (how close the lines are)

What are the equation for all waves?
1) waves speed (m/s) = frequency (Hz) x wavelength (m) { v=fxλ } 2) wave speed (m/s) = distance (m) ÷ time (s) { S=d÷t }
