# What is the formula of multiple reflection?

## What is the formula of multiple reflection?

The number of images of an object placed between two mirrors can be found from the following formula. When the angle between the mirrors is 90°, the number of images is (360/90°)-1 = 4-1 = 3. Similarly, when the angle is 60°, the number of images is (360/60°)-1=6-1 = 5.

## How do you form multiple images by using two plane mirrors?

Place both the mirrors vertically with 180 degree angle between the them. Place a lighted candle in the space between the two mirrors. You will see single image of the candle in mirror. Reduce the angle between mirrors and observe multiple images of the candle which makes a beautiful scene.

**How can we produce multiple reflections using mirrors?**

A mirror reflects everything in front of it including another mirror. If you place two mirrors at an angle, you increase the number of reflected images you can see. Depending on the angle you choose, you can see a number of unbroken reflections and one or more composite or partial reflections.

### How do you get 3 images of a single object one should have two plane mirrors at an angle of?

To get three images of a single object, one should have two plane mirrors at an angle of: A. 60∘

### What is the formula to find multiple images?

We can find the number of images formed if we know the angle between the plane mirrors. This is given by the formula: n= (360/ϴ) – 1 if 360/ϴ is even. n= 360/ϴ if it comes odd and when the object is placed asymmetrically.

**What do you mean by multiple reflection give one example?**

for example; when two mirrors are places parallel to each other and if a beam of light is passed then this beam of light will be incident on one mirror and the reflected ray from this mirror will be the incident ray for the second mirror by this way reflection occurs several time.

## What is the formula to find the number of images formed between two mirrors?

Formula for number of images formed by two plane mirrors incident at an angle θ is n = 360∘θ. If n is even, the number of images is n-1, if n is an odd number of images.

## How is multiple reflection caused?

Explanation. If a reflected light ray is reflected again on being incident on another surface, it is termed multiple reflections. Multiple reflections are used in periscopes. Periscopes are used in submarines, war tanks and by solders in bunkers to see objects that are not visible directly.

**How many plane mirrors are needed to produce multiple images?**

Two mirrors

Two mirrors can produce multiple images.

### What will be the number of images formed when an object is placed between two parallel mirrors facing each other?

Number of images formed in two parallel mirror are infinite because an image formed by one mirror can act as an object for the second mirror. And every image formed by the second mirror can act as an object for the first mirror. This image formation will continue for both the mirrors.

### When two plane mirrors are kept at 60 to each other we get?

five

(b) The number of images formed if an object is placed between two plane mirrors with an angle of 60°, is five. Five images are formed: i.e, the angle between two mirrors is 60°, n=360°/60° = 6, number of images = n-1 = 6-1 = 5.

**Where do you find multiple images formed by plane mirror?**

## What happens in multiple reflection of light by plane mirror?

In this, state the reflected light is reflected backward again from one mirror to another. When the two mirrors are put inclined at an angle to each other they can collectively form multiple images of the object in front. The above image shows the image formed by a plane mirror.

## How many images are formed in multiple reflection?

When an object placed is placed between two parallel plane mirrors, infinite images are formed as shown in the ray diagram.

**How do you find the number of reflections?**

Let d equal the horizontal distance traveled by the light between reflections off either mirror. Calculate the distance d by multiplying the separation distance by the tangent of the beam angle. Divide the total distance (168 cm) by d to calculate the total number of reflections.

### Why do plane mirrors form multiple images?

Multiple images of the same object are formed by two opposing flat mirrors because image formed in one mirror serves as object for the other mirror. These images appear to be progressively smaller due to distance of each from the eye or due to our perception.

### How many images are formed in multiple reflections?

**How many images are formed when two plane mirrors are placed?**

Two different images of the object will be formed in the two mirrors.

## How many times do two mirrors reflect at the same angle?

Two mirrors set at any angle between 180º and 90º reflect an object 2 times. As the angle approaches 90º, you see one mirror reflected in the other, but you do not see additional reflected objects. Click image to enlarge. Two mirrors at a right angle (90º) show two complete reflections and one composite reflection.

## What happens to the image produced by a mirror?

The remaining images are produced as the result of multiple reflections of light off more than one of the faces. Right angle mirrors will allow a maximum of two reflections of light from the object. But as the angle decreases, three, four, and even more reflections can occur.

**What happens when two plane mirrors are placed on one edge?**

If two plane mirrors are placed together on one of their edges so as to form a right angle mirror system and then the angle between them is decreased, some interesting observations can be made. One observes that as the angle between the mirrors decreases, the number of images that can be seen increases.

### How does the angle of refraction of a mirror change?

The number of complete and partial reflections changes as you view the mirror from different angles. Changing the angle of incidence (the line between your eye and the mirrors) changes the angle of refraction (the number of reflections you see).
