In Figure, find the total magnification after two successive reflections first ono `M_(1)` and then on `M_(2)`.

A

`+1`

B

`-2`

C

`+2`

D

`-1`

Text Solution

Verified by Experts

The correct Answer is:
C
For `M_(1):V=-60,m_(1)=-2`
For `M_(1):u=+20,F=10`
`(1)/(V)=(1)/(20)=(1)/(10)=V=20`
`:.M_(2)=-(20)/(20)=-1`
`:.M=m_(1)xxm_(2)=+2`
