Two flat mirrors have their reflecting surfaces facing each other ,with an edge of one mirror in contact with an edge of the other,so that the angle betweem the mirrors is`60^(@)`Find all the angular positions of the image with respect to x-axis .Take the case when a point object is between the mirrors at`(1,1)`point of intersection is`(0,0)`and`1^(st)`mirror is along x-axis.

Text Solution

Verified by Experts

The correct Answer is:
(I)`75^(@),(II)165^(@),(iii)195^(@),(IV)285^(@),(V)315^(@)`

So position of images are`75^(@),165^(@),195^(@),285^(@),395^(@)`
