Energy transferred mc change in t
Wave Velocity Frequency x Wavelength7y
Less Dense Medium to Denser Medium Slows down and bends towards the normal
Denser Medium to Less Dense Medium Speeds up and bends away from the normal
n(Calc) speed of light in a vacuum/speed of light in medium
n (Relationship) sini/sinr
Critical Angle Occurs when the angle of reflection = 90
TIR I= larger than c
n (Critical angle) n=1/sinc
Dispersion Definition The spreading out of light into the colours of the spectrum
