# What is perpendicular mirror?

## What is perpendicular mirror?

Perpendicular is the normal to the surface of mirror, about which we measure angle of incidence and angle of reflection. At the point of incidence where the ray strikes the mirror, a line can be drawn the perpendicular to the surface of the mirror. This line is known as a normal line.

What happens when two plane mirrors are kept perpendicular to each other?

Statement-I: When two plane mirrors are kept perpendicular to each other as shown in the figure (O is the point object), three images will be formed. Statement-II: In case of a multiple reflection, the image of one surface can act as an object for the next surface.

What happen when light is perpendicular to the mirror?

A light ray that strikes an object consisting of two mutually perpendicular reflecting surfaces is reflected back exactly parallel to the direction from which it came ((Figure)). This is true whenever the reflecting surfaces are perpendicular, and it is independent of the angle of incidence.

### How many images do 3 perpendicular mirrors form?

All the three mirrored walls are perpendicular, i.e x = 90 degrees. 3 + 4 = 7 images.

How many images will be formed by two perpendicular mirrors?

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

When two plane mirrors are kept at 90 degree we get?

When you place two plane mirrors at a 90-degree angle, the image of the first mirror is reflected in the second mirror so that the reversed mirror image is reversed again, and you see a true image.

## How many images will you see when two plane mirrors placed perpendicular to each other?

3 images
When two plane mirrors are kept perpendicular to each other as shown (O is the point object), 3 images will be formed.

What happens when a ray of light falls perpendicular on the surface of a plane mirror what is the angle of reflection in this case?

The correct answer is 90 degrees. If light falls perpendicularly on a plane mirror, what will be the angle at which it will be reflected at 90 degrees. In a plane mirror, At the point of incidence, the incident ray is reflected in such a way that the angle of reflection equals the angle of incidence.

What happens when the incident ray is perpendicular to the surface?

Refraction and reflection of light If the ray is perpendicular to the surface, then the incident ray, the reflected ray and the transmitted (refracted) ray all lie along the same line (i.e they are collinear). If the ray is not perpendicular to the surface, then the ray appears to be bent at the surface.

### How many images are formed if the two mirrors are kept at an angle of 90 degrees?

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 are formed when an object is placed between two plane mirrors kept perpendicular?

Three images
Answer: (a) The number of images formed when an object is placed between the two plane mirrors at an angle of 90°, is 3. Three images are formed. We know that two mirrors kept perpendicular to each other, produce three images for an object that is placed in between them.

How many images will you see when 2 plane mirrors are perpendicular to each other?

## What will happen to the image if two plane mirrors are held perpendicular to each other also comment on the no of images formed?

Answer : Three images are formed if the plane mirrors perpendicular to each other….

Is perpendicular to the plane of reflection?

Normal is defined as the perpendicular drawn to surface of plane mirror which is in the same plane as that of incident and the reflected ray.

What happens when a light ray falls perpendicularly on a glass slab?

Light falling perpendicularly on glass slab When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero.

### What happens when incident ray is perpendicular to the glass slab?

If the incident ray falls on the glass slab perpendicularly or normally, it goes inside the slab un-deviated i.e there is no bending of light because of the following reasons: As the incident rays passes along the normal to the surface, the angle of incidence becomes zero.

When a incident ray of light is perpendicular to the surface at point of incidence?

When light is an incident perpendicular in the surface, what is the angle of incidence? Zero. In geometric optics , the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal . A ray of light is incident at 45 degrees.

How many images do two perpendicular mirrors form?

## Why are 3 images formed when the mirrors are placed at an angle of 90 degree to each other?

Expert-verified answer n=360°/theta when object is asymmetrical. and 360°/90°=4 which is even so we will subtract 1 . Hence, 3 images will be formed if two plane mirrors placed at angle 90 degree.

How many images are formed by perpendicular mirrors?

When two plane mirrors are kept perpendicular to each other as shown (O is the point object), 3 images will be formed.

What is mirror in physics?

In physics, a mirror is defined as a surface which reflects nearly all kinds of light incident on it. Moreover, A mirror will keep on reflecting light in a regular fashion until or unless an opaque object is introduced between the reflecting surface and the source of light.

### What is an example of a spherical mirror?

A prime example of a spherical mirror is the reflectors present inside table lamps. These mirrors are concave mirrors which help to direct illumination towards a given area.

Why is a mirror a reflective surface?

Here, mirrors reflect the light energy. The reason why only mirrors reflective and not the other flat white surface is because the mirror is smooth at a microscopic level. When the light energy hits the rough surface, the light bounces back in all direction and this is known as diffuse reflection.

What is the law of reflection for mirrors?

A mirror is defined as reflecting surface and can be explained by the law of reflection, which states that when a ray of light is made to fall on the reflecting surface, the reflected ray has its angle of reflection, incident ray, and the reflected ray are normal to the surface at a point of incidence.
