Question

what is total internal reflection (TIR)​

Answer 1

Explanation:

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.

Answer 2

Answer:

TOTAL INTERNAL REFLECTION WAS DISCOVERED BY Johannes Kepler

Formula: 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.
