Worked practice questions

As per your syllabus, what is the refractive index of DIAMOND — the HIGHEST among the common materials listed?

  1. 1.52
  2. Less than 1
  3. 2.42
  4. 1.33
Show answer and solution

Correct answer: C. 2.42

As per your syllabus, diamond n = 2.42 — highest refractive index among listed materials. Its sparkle is partly due to this high refractivity + total internal reflection.

As per your syllabus, what is the OPTICAL CENTRE of a lens?

  1. The focal point
  2. The radius of curvature
  3. A point on the lens edge
  4. A point on the principal axis through which a ray passes WITHOUT deviation
Show answer and solution

Correct answer: D. A point on the principal axis through which a ray passes WITHOUT deviation

As per your syllabus, optical centre = point of no deviation. Rays through it pass undeviated.

As per your syllabus, Physics, what is the LENS FORMULA?

  1. 1/v − 1/u = 1/f
  2. 1/v + 1/u = 1/f (this is the mirror formula)
  3. v + u = f
  4. v − u = f
Show answer and solution

Correct answer: A. 1/v − 1/u = 1/f

As per your syllabus, Eq 9.8, lens formula = 1/v − 1/u = 1/f. Mirror formula has + sign.
