What is the magnification of concave mirror and convex mirror?

Magnification of a convex mirror is always positive, but that of a concave mirror may be both positive or negative.

Is magnification of concave mirror negative?

Magnification is negative in a concave mirror. The magnification of a concave mirror is given by the ratio of the height of the image to the height of the object. Hence, if the image is inverted and real the magnification will be negative.

What is the magnification for convex mirror?

As the object will get closer to the mirror the image will get bigger and bigger but it will not get bigger than the original object. So, the image formed in a convex mirror is always virtual and diminished. So, the magnification of a convex mirror is always less than 1.

What is magnification for a concave mirror Class 10?

In a concave mirror, when the distance of the object is less than the focal length, the magnification will be greater than one. When the distance of the object is greater than the focal length, then the magnification is less than one.

Can a concave mirror have a magnification of 1?

(a) The object must be at the centre of curvature of concave mirror. The image formed is real, inverted and of the same size as the object. That is why magnification = – 1.

What is magnification formula for mirror?

Magnification (m) = h/h’ And h’ is the image height and h is the object height.

How do you calculate the magnification of a concave mirror?

1. The mirror formula is 1f=1v+1u.
2. The magnification m is given by m=−vu.
3. According to sign conventions, for a concave mirror, the focal length (f) is negative, the object distance (u) is negative, the image distance (v) is positive for a virtual image and negative for a real image.

What is the magnification of concave lens?

A concave lens always forms virtual, erect, and diminished image irrespective of the position of the object. Hence, the magnification is always is positive, but less than 1.

What is the magnification formula of mirror?

What is the focal point of a concave mirror?

A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point.They are used to focus light.

What are the characteristics of a convex mirror?

Convex mirrors. A convex mirror diagram showing the focus, focal length, centre of curvature, principal axis, etc. A convex mirror, diverging mirror, or fish eye mirror is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light.

What is the difference between concave and convex?

The major difference between concave and convex lenses lies in the fact that concave lenses are thicker at the edges and convex lenses are thicker in the middle. These distinctions in shape result in the differences in which light rays bend when striking the lenses.

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.
