Laws of Refraction
Total Internal reflection happens only when light is travelling from an optically denser medium to an optically rarer medium.
In Snell’s law,
sinisinr = v1v2 = constant
This constant is called as:
none of these
- in different planes
- in the same plane
- in mutually perpendicular planes
- at an angle of 45∘ to each other
How is refractive index of a medium 2 given with respect to medium 1 related to speed of light?
where, n1 and n2 are the respective refractive indicies of medium 1 and medium 2. And, c1 and c2 are speed of light in medium 1 and medium 2 respectively.
None of these
n1 – n2 = v2 – v1
