I doubt it, not many people do summaries in yr 11

We have to make summaries for all our topics, as since our teacher likes to practice what he calls the lecture approach to learning (bah) . I've got a summary of 8.2 (looking for 8.4 now!!), but I only wrote the required experiments up separately... there are a few sites on the net..*not that i can remember them exactly

The world communicates:

Waves can be categorized as:

- Mechanical waves (consisting of particles with energy, which require a medium in order to travel)
- Electromagnetic waves, which do not require a medium

A wave consists of 2 motions:

1) A uniform motion in the direction of wave travel; this is the direction of energy transfer.
2) A vibration of particles or fields about an equilibrium or central point.

The vibration disturbance component of the wave may occur:

- At right angles (90) to the direction of propagation; these waves are called transverse waves.
- In the same direction as the direction of propagation; these waves are called longitudinal waves.

For transverse and longitudinal waves, V = f and F = 1/T

Waves transmit energy but do not transfer matter
