Dear sir,
1.In lecture 6 solution, the inner refracting angles(which you have denoted by theta) as equal.But here the inner refracting angles i.e r1 and r2 are not equal?? why is that so
2.In lecture 4 you have used Snell's law for the whole path of light but here you have divided the Snell's law for two different surfaces which have different constants? Why is that
