(360/Angle)-1

example: angle= 60

then,

(360/60)-1=5

infinite number of images are formed in both the mirrors if the mirrors are kept parallel

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.

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.

Three images will be formed

The empirical formula for the number of images formed by two inclined mirrors is [ n = \frac{360}{|180-\theta|} ], where (\theta) is the angle between the mirrors. This formula is derived from the concept that each additional image is created when the extended reflected light rays meet at intervals of (\frac{360}{|180-\theta|}) degrees.

4.5 or 3.5 The number is five.

The number of images of an object placed between two mirrors inclined at an angle is give by:Number of images= (360/ angle of inclination)-1

To identify an image on inclined mirrors, you need to follow the laws of reflection. The angle of incidence is equal to the angle of reflection, so you can trace the path of light rays as they reflect off the mirrors to determine the position and characteristics of the image. Remember that the image formed will appear to be the same distance behind the mirror as the object is in front of it.

To determine the number of images formed by a mirror, you need to consider the distance of the object from the mirror and the type of mirror (concave or convex). For a plane mirror, only one image is formed which is virtual and upright. For concave and convex mirrors, the number of images formed can vary depending on the position of the object relative to the focal point, center of curvature, and the mirror's surface.

No. They will look different.

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.
