The point C denotes the centre of curvature of the curved surface of refractive index 1.5. An object O is placed in air at a distance of 15 cm. Location of the image will be –
Text Solution
Verified by ExpertsThe correct answer is:
A
Here u = – 15 cm, R= + 30 cm, μ 1 = 1 and μ 2 = 1.5
= 
⇒ 
– 
= 
⇒ 
+ 
= 
= 
⇒ 
= 
– 
⇒ v = – 20 × 1.5 = – 30 cm
so image is formed 30 cm left to the spherical surface and is virtual erect.
