When a biconvex lens of glass having refractive index 1.47 is depped in a liquid it acts az a plane sheet of glass. This implies that the liquid must have refractive index

A

greater than that of glass

B

less than that of glass

C

equal to that of glass

D

less than one

Text Solution

Verified by Experts

The correct Answer is:
C
`(1)/(f)=((mu_(2))/(mu_(1))-1)((1)/(R_(1))-(1)/(R_(2)))`
For power `=(1)/(f)=0, mu_(2)=mu_(1)`
