If 2 mirrors are placed perpendicular to each other then infinite no of images will be formed because image formed by one mirror will act as the object for the other and vice verse.
Due to multiple reflection!

Use the formula [360/@]-1@ is the angle of inclination of the two mirrors.Suppose we keep the two mirrors in the same line, then @ = 180So there will be only one image.If suppose we keep two mirrors parallel to each other, then @ = 0 so infinite images.Now in your case @ = 45So 7 images will be seen.
Recursion is the process or act in which the person repeats its acts in a definite way. Like the images in two mirrors, kept par all to each other. There is a Never-Ending Image formed in both the mirrors.
Given two lines, each is perpendicular to the other if the angles formed at the vertex are 90 degrees.
Since no of images = 360/theta -1 then 360/90-1 4-1 == 3
As we place two mirrors inclined with each other then many images are formed. If @ is the angle of inclination then number of images is got by the formula [360/@] - 1 Hence as we place the two mirrors at right angles ie 90 degree then number of images will be 3 If both mirrors kept parallel facing each other then infinite images are formed.
Virtual images.

If the mirrors are exactly parallel - there will be an infinite number of images, as they will be reflected indefinitely.
To find out how many images are formed when plane mirrors are tilted at an angle, use the formula N=360/a-1 , wherein N is the number of images formed and a is the given angle. So in this case, N=360/30-1, will result to N=11 images formed.

In theory, there should be infinitely many images. In practice, though, imperfections in the mirrors, diffusion in glass and the air gap between the mirrors mean that there are not infinitely many images.
With two mirrors at right angles you will have 3 (360/90 - 1) images of an object. Two of these are primary and the third is secondary. Some light rays from the object bounce of each of the mirrors to your eye to form the two primary images. But there are other rays that bounce off a mirror onto the second mirror before they get to you. This produced the secondary image.
Use the formula [360/@]-1@ is the angle of inclination of the two mirrors.Suppose we keep the two mirrors in the same line, then @ = 180So there will be only one image.If suppose we keep two mirrors parallel to each other, then @ = 0 so infinite images.Now in your case @ = 45So 7 images will be seen.
