Two refracting media are separated by a spherical interfaces as shown in the figure. AB is the principal axis, `mu_1 and mu_2` are the refractive indices of medium of incidence and medium of refraction respectively. Then,

A

if`mu_(2)gtmu_(1)`.then there cannot be a real Image of real object.

B

if`mu_(2)gtmu_(1)`.then there cannot be a real Image of virtual object.

C

if`mu_(1)gtmu_(2)`.then there cannot be a virtaul Image of virtual object.

D

if`mu_(1)gtmu_(2)`.then there cannot be a real Image of real object.

Text Solution

Verified by Experts

The correct Answer is:
A,C

` (mu_(2))/(v)-(mu_(1))/(u)=(mu_(2)-mu_(1))/(R )`
(A) if `mu_2gtmu_1`
`(mu_(2))/(v)-(mu_(1))/(-u)= -ve`
`(mu_(2))/(v)=-Ve-(mu_(1))/(u)rArr v is -Ve`
(C )if `mu_(1)gtmu_(2)`
`(mu_(2))/(v)-(mu_(1))/(u)+Ve rArr (mu_(2))/(v)=+Ve+(mu_(1))/(u) rArr v "is" +Ve`
