Medium- what the wave travels through Ex. Water, spring, string, air

Longitudinal waves- sound waves, seismic waves or pressure waves

Transverse waves- electromagnetic waves

Waves

Reflection: bounce off a surface

Refraction: bend through an object

Diffraction: waves wrapping around an edge

Wave Movement

Resonance: vibrations caused by waves

Polarization: filters block out certain wavelengths and allow only certain waves through

Standing Waves Between two

barriers- node on each end. At the nodes, the wave changes direction.

Interference Interference when two

or more waves meet Constructive

interference- waves add get bigger

Destructive interference- waves get smaller and cancel out
