Topics 6
- Partial reflection and refraction; laws of refraction; effect on speed, wavelength and frequency
- Refractive index: mu = c/v and v = f x lambda; typical values for water, glass and diamond
- Refraction through a rectangular glass block; lateral displacement; multiple images in a thick mirror
- Real and apparent depth; apparent bending of a stick in water
- Refraction through a triangular prism; deviation
- Critical angle and total internal reflection (mu = 1/sin C); conditions; TIR in triangular prisms (60-60-60, 30-60-90, 45-45-90); comparison with plane-mirror reflection
