A planoconcave lens is placed on a paper on which a flower is drawn. How far above its actual position does the flower appear to be -
Text Solution
Verified by ExpertsThe correct answer is:
A
Considering refraction at the curved surface.
u = –20 ; µ 2 = 1
µ 1 = 3/2 ; R = + 20
applying 
– 
= 
⇒ 
i.e. 10 cm below the curved surface or 10 cm above the actual position of flower.
