two plane mirror `L_(1) and L_(2)` are parallel to each other and 3m apart. A person standing x m from the right mirror `L_(2)` looks into this mirror and sees a series of images, The distance between the first and second image is 4 m. Then, the value of x is

A

`2m`

B

`1.5m`

C

`1m`

D

`2.5m`

Text Solution

Verified by Experts

The correct Answer is:
C

`I_(1)I_(2)=(3-x)+(3)+x`
`=4m`
Solving we get , x=1m.
