- A progressive wave carries energy from one place to another without the transfer of material.

- A wave makes is caused by the osciallation of particles or fields at a source.

- Waves can be reflected, refracted or diffracted.

Reflection: When the wave hits a boundary and bounces back

Refraction: The Wave changes direction as it enters a different medium.

Diffraction: A wave spreads through a gap or around an obsticle

- Waves have lots of different quantities:

Displacement, x (m) - How far it has moved from it's undistributed point

Amplitude, A (m) - Maximum magnitudinal displacement

Wavelength, l (m…
