All objects referred to the subsequent problems lie on the principal axis.

If light is incident on surface `1` from left, the image formed after the first refraction is definitely :

A

Real for a real object

B

Virtual for a real object

C

Real for a virtual object

D

Virtual for a virtual object

Text Solution

Verified by Experts

The correct Answer is:
B
`(mu_(2))/(v)=(mu_(1))/(u)+((mu_(2)-mu_(1))/(R))`
`(mu_(2)-mu_(1))` is `+ve` and `R` is `-ve` if `u` is `-ve,v` will always be `-ve`
i.e. for real object image is always virtual.
