Question

if the angle between two inclind plane mirrors is 45 degree find the number of images formed ​

Answer 1

Answer:

7 Images formed

Explanation:

No. of Images formed = 360 / angle between mirrors

Angle between mirrors =  45 degrees

Therefore = 360/45

                = 8

Now,

If 360/angle between mirrors = even no.

Then,

 No. of Images formed = even no. - 1  [No idea why, but it's the formula]

Thus, the no. of images = 8 - 1

                                     = 7                         Ans.

Hope it helps!
