Question
How are concave and convex mirrors constructed?
✓
Answer
The given part of a hollow spherical glass can be converted into a concave mirror by (i) polishing (silvering) its inner side (inner surface or concave surface) to make it reflecting or (ii) coating its outer side with a thin layer of silver and painting it with red colour to protect the silver coating.
[Note: Case (i) corresponds to the front surface silvered concave mirror.]
[Note: Case (i) corresponds to the front surface silvered concave mirror.]
