In the figure shown a point object O is placed in air. A spherical boundary separates two media. AB is principal axis. The refractive index above AB is 1.6 and below AB is 2.0. The separation between the images formed due to refraction at spherical surface is –
A
12 m
B
20 m
C
14 cm
D
10 m
Answer
12 m
Explanation
Solution
Use refraction formulae separately that is for air and m = 1.6 and for air m = 2.0 and find the position of the two images
