Question

When incident angle i satisfies n = \frac{1}{\sin i}, the refracted light will pass along the surface. [True/False]

Answer 1

Answer:

False

Explanation:

Statement : n = 1/sin i.

n = sin i/sin r........eq. 1

since, refracted light passes along the surface,

which implies Angle r = 90°

and sin 90° = 1

Put 1 in eq. 1,

n = sin i/1 or n = sin i.

but the given statement is n = 1/sin i.

Therefore, the answer is false.
