- 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…
