Physics
When a ray of light travels from substance A to substance B and reaches their boundary, it suffers total internal reflection. Out of the following possibilities, which one is correct?
| Angle i | Substance B | |
|---|---|---|
| (a) | i < C | Optical density of A is less than B |
| (b) | i = C | Optical density of A is more than B |
| (c) | i > C | Optical density of A is less than B |
| (d) | i > C | Optical density of A is more than B |
- Option (a)
- Option (b)
- Option (c)
