Consider a point object situated at a distance of \(30 \mathrm{~cm}\) from the centre of sphere of radius \(2 \mathrm{~cm}\) and refractive index 1.5 as shown in the figure. If the refractive index of the region surrounding this sphere is 1.4 , then the position of the image due to refraction by sphere with respect to the centre is
- A \(30 \mathrm{~cm}\)
- B \(45 \mathrm{~cm}\)
- C \(\infty\)
- D \(28 \mathrm{~cm}\)
Answer & Solution
Correct Answer
(A) \(30 \mathrm{~cm}\)
Step-by-step Solution
Detailed explanation
(Note If we takes, \(n_2=1.4\) and \(n_1=1.5\), then we get option 1 as answer) For first surface, \(n_1=1.5, n_2=1.4\)…
