 A transparent sphere of radius R and refractive index m. An object O is placed at a distance x from the pole of the first surface so that a real image is formed at the pole of the exactly opposite surface.

If an object is placed at a distance R from the pole of first surface, then the real image is formed at a distance R from the pole of the second surface. The refractive index m of the sphere is given by
  • a)
    1.5
  • b)
    2
  • c)
  • d)
    None
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Atransparent sphere of radius R and refractive index m. An object O is...

From the symmetry of the fig.ray inside the sphere is parallel to the principal axis. Taking refraction at A
2/v)−(μ1/u))=(μ2−μ1)/R
(μ/∞)−(1/−R)=(μ−1)/R
(1/R)=(μ−1)/R⇒μ−1=1
μ=2
