Question
For a spherical mirror, a normal line at a point is drawn _____.
- From the point at any angle
- Perpendicular to the tangent at that point
- Parallel to the tangent at that point
Convex lens
- None of the above
Hint:
Perpendicular to the tangent at that point
The correct answer is: Perpendicular to the tangent at that point
for a sperical mirror we can draw a perpendicular to the point on the mirror, which will give us the normal.
