A concave spherical surface of radius of curvature \(10 \mathrm{~cm}\) separates two medium x & y of refractive index \(4 / 3 \& 3 / 2\) respectively. If the object is placed along principal axis in medium X then
- image is always real
- image is real if the object distance is greater than \(90 \mathrm{~cm}\)
- image is always virtual
- image is virtual if the object distance is less than \(90 \mathrm{~cm}\)
Answer
(C) image is always virtual
