An object is placed at the centre of curvature of a concave mirror. The image formed is

  1. real, inverted, diminished, beyond C
  2. at infinity
  3. virtual, erect, magnified
  4. real, inverted, same size, at C
Show answer and solution

Correct answer: D. real, inverted, same size, at C

For an object at C ($u=2f$), the mirror forms a real, inverted image of the same size, also located at C.

As per your syllabus, what is FOCAL LENGTH (f) of a spherical mirror?

  1. Half the aperture
  2. Twice the radius of curvature
  3. The distance between the POLE (P) and the PRINCIPAL FOCUS (F)
  4. Distance from pole to centre of curvature
Show answer and solution

Correct answer: C. The distance between the POLE (P) and the PRINCIPAL FOCUS (F)

As per your syllabus, f = distance PF. R = 2f relates focal length to radius of curvature.

The refractive index of a medium compares the speed of light in:

  1. the medium to the object
  2. vacuum to that in the medium
  3. air to water only
  4. two mirrors
Show answer and solution

Correct answer: B. vacuum to that in the medium

Refractive index = speed of light in vacuum ÷ speed of light in the medium.
