Solution
A ray of light passes from one medium to another medium. Refraction takes place when angle of incidence is 45°.
Explanation:
- Refraction happens when a light ray travels from one medium to another with a differing optical density.
- This bending of light occurs when the angle of incidence is greater than 0° but less than 90°.
- If the angle of incidence is 0°, light flows through without bending.
- At 90°, light travels along the boundary without entering the second medium.
Therefore, refraction can take place at an angle of incidence like 45°, but not at 0° or 90°.
