Hi user!

For two mirrors kept at an angle x, the number of images n is determined by the formula 360/x.

If n turns out to be odd,

We have the following two cases:

Asymmetrically

--------------------

Number of images=n

Symmetrically

------------------

Number of images=n-1

And if n turns out to be even,

Number of images= n-1 for all positions of object

Now, coming back to your question,

Here x=50

n=360/x

=360/50

=7.2

Rounding off,n=7

Now,n is odd.

(1) Asymmetrically

number of images=n

=7

(2) Symmetrically

number of images= n-1

= 7-1

=6
