Question
A ray of light A incident from air suffers partial reflection and refraction at the boundary of water.
- Complete the diagram showing (i) the reflected ray B and (ii) the refracted ray C.
- How are the angles of incidence i and refraction r related?
Solution
- It shows the refracted beam DC and the reflected ray DB.
- `sin i/sin r = μ` is the relation.
