Refraction by medium

Asked by Rahul Kumar | 22nd Sep, 2012, 11:34: AM

Expert Answer:

what u r writing as refraction is refractive index
and when the incident light is parallel to the normal, the incident angle and refracted angle is zero which mean it did not undergo any refraction but
is just tranmitted.
hence the formula is not valid in that case.
