A point object is held between two plane mirror held at `(i) ` `24^(@)` `(ii)` `30^(@)`. What is the number of images formed in the two cases ?

A

`(i) = 15 , (ii) = 11`

B

`(i) = 12 , (ii) = 11`

C

`(i) = 11 , (ii) = 12`

D

`(i) = 11 , (ii) = 15`

Text Solution

Verified by Experts

The correct Answer is:
A
(i) When `theta = 24^(@)`
`n = (360)/(theta) = (360)/(24) = 15`
(ii) When `theta = 30^(@)`
`n = (360)/(theta) -1 = (360)/(30) - 1 = 12 - 1 = 11`
