1. Total internal reflection:

When the incident angle $Φ_1$ is higher than critical incident angle $Φ_c$ the whole path of the light is reflected back in the first medium. This is known as Total Internal Reflection (TIR).

$Φ_1 \gt Φ_c…………. $ Condition for TIR

1. Acceptance angle:

Maximum angle to the axis …
