To summarise
| Position of the object | Position of the image | Nature of the image |
|---|---|---|
| At infinity | At the focus F, behind the mirror | Virtual and erect |
| Between infinity and the pole P of the mirror | Between P and F, behind the mirror | Virtual and erect |
What is convex mirror explain with diagram?
Convex Mirror is a curved mirror where the reflective surface bulges out towards the light source. In this diagram, the center of the original sphere is called as the center of the curvature (C) and the line that passes from the mirror’s surface through the sphere’s center is called as the principal axis.
What is the ray diagram of convex mirror?
The ray diagram above illustrates that the image of an object in front of a convex mirror will be located at a position behind the convex mirror. Furthermore, the image will be upright, reduced in size (smaller than the object), and virtual. This is the type of information that we wish to obtain from a ray diagram.
What type of image is formed by convex mirror?
virtual and erect
Image formed by a convex mirror is always virtual and erect. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller.
What are the 2 cases of convex mirror?
Rules for Image Formation in a Convex Mirror
- Rule 1:
- Rule 2:
- Rule 3:
- Rule 4:
- Case 1: When object is placed at Infinity.
- Case 2: When object is placed anywhere on the principal axis.
What is convex mirror Short answer?
A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. The image is smaller than the object, but gets larger as the object approaches the mirror.
What are the rules of convex mirror?
For a convex mirror, if the object is at infinity the image will be a dot on the focal point. As the object moves from infinity toward the mirror, the image moves along the principal axis toward the mirror. When the object is right next to the mirror, the image will be right next to the mirror on the other side.
Can a convex mirror ever form a real image explain with diagram?
A convex mirror used alone cannot produce a real image. All images formed are virtual images. However, real images can be produced in more complicated optical systems, if the object is virtual.
What are the features of the image formed by a convex mirror?
The characteristics of image formed by convex mirror are:
- The image formed is a virtual image.
- The image is formed behind the convex mirror.
- The image formed is smaller than the object.
- The image is an upright and erect image.
What are the 4 rules of convex mirror?
How can we make convex mirror?
How to Make a Convex Mirror Spray paint the ceiling medallion. It took two coats for me to get sufficient coverage over the dark brown. Glaze the ceiling medallion using Burnt Umber craft paint that has been thinned down with just a tiny amount of water. Very carefully, remove the mirror from the metal encasing by first cutting away the rubber gasket with the box cutter.
What are the main functions of convex mirrors?
Side-view Mirrors. Convex mirrors are used as side-view mirrors in vehicles.
What is an example of a convex mirror?
The most commonly seen example of a convex mirror is the side view mirror on a car. Convex mirrors are seen in dome mirrors found in offices and stores for security and anti-theft purposes.
Why is convex mirror used as rear view mirror?
A convex mirror is used as rear view mirror because they form erect, virtual, and diminished images which allow the driver to view a large area in a small mirror.
