REFRACTION PRODUCED BY A PARALLEL SIDED SLAB

  When a ray of light travels from one medium to a second medium, refraction occurs at both the interface at point ‘B’ and then once again refraction take place at point ‘C’ from lower interface. By Snell’s law, (at point ‘B’)         ………………….(1) and (at point ‘C’) Or                         ………………….. (2) From (1) and (2) […]
