Object placed between two parallel plane mirrors form infinite images. Hence, infinite images of the candle will be formed.

Q14) How many images of a candle will be formed if it is placed between two parallel plane mirrors separated by 40 cm? Solution: Infinite images are formed when two plane mirrors are placed parallel to each other, irrespective of the distance.

When two mirrors are placed parallel to each other, then an infinite number of images are formed. Hence, Infinite images of the candle will be formed because of multiple reflections between the mirrors.

Interestingly, a single mirror produces a single image; another single mirror produces a second image; but when you put the two single mirrors together at right angles, there are three images.

If the mirrors are inclined at 60°, a hexagonally symmetrical pattern results from one object producing six regularly placed images. A simple kaleidoscope consists of two thin, wedge-shaped mirror strips touching along a common edge or of a single sheet of bright aluminum bent to an angle of 60° or 45°.

If the image of the object is viewed in two plane mirrors that are inclined to each other, more than one image is formed. The number of images formed by two plane mirrors depends on the angle between the mirror.

virtual image

The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.

An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected. So, light incident on any smooth shiny surface like a mirror bounces back into the same medium. This bouncing of light by any smooth surface is called reflection of light.

Image Formation By Convex Mirror The image formed in a convex mirror is always virtual and erect, whatever be the position of the object.

The image is erect because the light rays remain parallel before and after reflection meaning they never pass through a focal point . The image formed by the plane mirror is always behind the mirror and the rays neither converge nor diverge from the surface which is what observed as in the case of curved mirrors.

Answer: Real images (images on the same side of the object) are always inverted. Explanation: Virtual images (images on opposite side of an object) are always erect/ upright.

The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. …

The image is laterally inverted. The size of the image is the same as the size of the object. The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror.

The image formed by a plane mirror is laterally inverted, upright, of the same size and is formed far behind the mirror as the object is in front of it.

virtual images

Complete answer: When the light rays from a source of light strike the surface of a concave mirror then it converges the light rays to a single point. Since the image formed on the cinema screen is always formed due to the actual meeting of rays, so a concave mirror is used on a cinema screen.

While a movie character often begins in someone’s imagination, the character’s image on the screen is a real image. Light rays shine onto the movie screen to produce the image we see as a moving picture.

A real image is formed on a cinema screen. Hence, the real and laterally inverted image is formed on cinema screen.

(i) Plane mirror forms virtual image. (ii) On cinema screen, real image is formed.

The image formed by a plane mirror is always virtual and erect. The size of the image is equal to that of the object. The image formed is as far behind the mirror as the object is in front of it. The image is laterally inverted.
