Two mirros are inclinded by an angle `30^(@)`. An object is placed `10^(@)` with the mirror `M_(1)`. Find the positons of first two images formed by each mirror. Find the total number of images using (i) direct formula and (ii) counting the images.

Text Solution

Verified by Experts

Figure is self expantory/
Number of images
(i) Using direct formula : `(360^(@))/(30^(@)) = 12` (even number)
`:.` Number of images `= 12 - 1 = 11`
(ii) By counting See the folloiwng table
