# When a thick plane mirror form multiple images due to multiple reflection image is the brightest one?

## When a thick plane mirror form multiple images due to multiple reflection image is the brightest one?

Answer: the case of a thick plane mirror, reflection takes place at the two surfaces, (top and bottom surfaces) and images are formed due to both. The second surface is silvered and therefore the second image is the brightest.

When a lighted candle is held in front of a thick plane glass mirror?

Complete answer: When a beam of light from a lit candle strikes the surface of a dense plane glass mirror, a small portion of the light (nearly 4\% ) is reflected, creating a faint virtual image, while the majority of the light (nearly 96\%) is refracted within the glass, forming a second image.

When a lighted candle is held in front of a thick plane glass mirror several images can be seen but the second image is the brightest give reason?

The second image formed due to the first refraction is the brightest because it is formed due to the light suffering strong reflection at the silvered surface below.

### Why does a thick plane mirror give a large number of images of a candle flame when seen obliquely?

Complete answer: This is due to the partial reflection at the first surface and actual reflection at the last surface of the glass mirror. When the light ray incident on the surface of the flat thick mirror, it undergoes partial reflection and refraction.

When two mirrors are kept at right angles how many images are formed?

three images
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.

How many images will be formed when the object is placed symmetrically between the mirrors angle between the mirrors is 72?

The number of images formed if two plane mirrors are kept at an angle θ is given by, 360oθif360oθ 360 o θ i f 360 o θ is odd and it is given by 360oθ−1if360oθ 360 o θ − 1 i f 360 o θ is even. For θ = 72o, number of image is 360o72o=5 360 o 72 o = 5 as 360o72o=5 360 o 72 o = 5 is an odd number.

## What is the power of a plane mirror?

zero
Hence, the power of the plane mirror is zero. Note: S.I unit of power is Dioptres. If the focal length is small then the power of the mirror is large and if the focal length is large then the power of the mirror is small.

How multiple images are formed by a thick plane mirror?

Multiple image formation in a thick plane mirror In case if the thick mirror being used, one may find that the incident ray and reflected ray do not meet at the same point on plane of separation of medium. This is because of the formation of multiple images due to multiple reflection.

What is a thick plane mirror?

In the case of a thick plane mirror, reflection takes place at the two surfaces, (top and bottom surfaces) and images are formed due to both. The second surface is silvered and therefore the second image is the brightest.

### Why are multiple images formed when two mirrors are placed at right angles to each other Class 8?

Answer: When two mirrors are placed at angles to each other we get multiple images because the image formed by one mirror acts as an object for the second mirror. This continues till no more reflection by either mirror is possible. Two mirrors placed at right angles (90°) to each other will form actually 3 images.

Why are infinite images not seen when two plane mirrors are facing each other?

Infinite images are not seen when two plane mirrors are facing each other because: After every successive reflection, some amount of light energy is absorbed. Thus luminosity of the image goes on decreasing, till they are no longer visible.

Why is the brightest image formed in a thick plane mirror?

In the case of a thick plane mirror, reflection takes place at the two surfaces, (top and bottom surfaces) and images are formed due to both. The second surface is silvered and therefore the second image is the brightest. Further images are formed due to multiple reflections and due to absorption of light by medium the images become fainter.

## Why is the second image always the brightest while the others?

Why is the second image always the brightest while the others are of diminishing brightness when there is a formation of multiple images in a thick plane glass plate or thick mirror? When an object is observed through a thick mirror, silvered at its back, a large number of images are obtained.

How are two images formed in a mirror?

In this case, the first image is formed by reflection at the first surface, which is the unsilvered surface of the mirror. The second image is formed after reflection from rear silvered surface, which sends maximum amount of light. Rest of the images formed are due to internal multiple reflections which occur inside the mirror.

What is the brightest part of the image formed by reflection?

When an object is observed through a thick mirror, silvered at its back, a large number of images are obtained. Out of all the images, the second image is the brightest. In this case, the first image is formed by reflection at the first surface, which is the unsilvered surface of the mirror.
