Worked practice questions

The mid point (geometric centre) of a spherical mirror is called its

  1. pole
  2. focus
  3. vertex
  4. rim
Show answer and solution

Correct answer: A. pole

1. A spherical mirror is a slice of a large sphere. 2. Its geometric mid point, lying on the surface, is the pole (P). 3. The focus and centre of curvature sit on the axis, not at the surface mid point. _Source: AP/TS SCERT Class 10 Physical Science, "Reflection of Light at Curved Surfaces"_

For a concave mirror the focus and centre of curvature lie

  1. behind the mirror
  2. in front of the mirror
  3. upon the surface
  4. at infinite distance
Show answer and solution

Correct answer: B. in front of the mirror

1. A concave mirror reflects from its inner, caved-in surface. 2. Parallel rays actually converge on that side. 3. So both F and C lie in front of the mirror. _Source: AP/TS SCERT Class 10 Physical Science, "Reflection of Light at Curved Surfaces"_

The relation between radius of curvature R and focal length f of a spherical mirror is

  1. f = 2R
  2. R = f
  3. R = 2f
  4. R = f/2
Show answer and solution

Correct answer: C. R = 2f

1. The focus is where paraxial parallel rays meet after reflection. 2. Geometry places it midway between the pole and centre of curvature. 3. So the radius of curvature is twice the focal length, R = 2f. _Source: AP/TS SCERT Class 10 Physical Science, "Reflection of Light at Curved Surfaces"_
