The critical angle of refraction for calcite is 68.4 when it forms a boundary with water. Use this information to determine the speed of light in Calcite. Assume the refractive index of water ,1.333, is less than the refractive index of calcite.

Using the law of Snell withN2=1.33 for waterN1 sin A1= N2 sin A2 = N2N1= 1.33/sinAso, the speed of light in clctie = (3*10^8 m/s) / 1.43= 1*10^8 m/s
