Question

. What questions do you pose to understand the concept of total internal reflection?​

Answer 1

Answer:

n1 sin θ1 = n2. θc=sin−1(n2n1) θ c = sin − 1 ⁡ ( n 2 n 1 ) for n1 > n2.

Total internal reflection occurs for any incident angle greater than the critical angle θc, and it can only occur when the second medium has an index of refraction less than the first.
