To get three images of a single object, one should have two plane mirrors at an angle of

A

`120^(@)`

B

`90^(@)`

C

`30^(@)`

D

`60^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`n=(360^(@))/(theta)-1 therefore 3=(360^(@))/(theta)-1`
`therefore (360^(@))/(theta) =4 therefore theta =90^(@)`
