Question
A concave spherical surface of radius of curvature 10 cm, separates two medium X and Y of R. I 4/3 and 3/2 respectively. If the object is placed along principle axis in medium X, then :
Options
A.image is always real
B.image is real if the object distance is greater than 90 cm
C.image is always virtual
D. image is virtual if the object distance is less than 90 cm
Solution
So v =
× - (ve)So for any value of u, v is (-ve). So image is virtual.
