1
Q
properties of em wave
8m
A
traverse waves travel to vacuum transfer Energy from 1 place to another travel at 3.0x10'8 m/s in vacuum wave speed eqn v=focus applicable when travel from 1 medium to another , •speed and wavelength change •freq no change obeys law of reflection and refraction carry no electric charge
