What position in a concave mirror the magnification is 1?

centre of curvature
(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 the position of the object when magnification is 1?

When the object is kept at 2f the magnification will be -1.

What is the type of the mirror if the magnification is 1?

The magnification of a mirror is -1. Hence, the image formed is real and inverted.

What is magnification What it reveals that magnification is +1?

Magnification = height of the image/height of the object = distance of the image/distance of the object. The magnification produced by a plane mirror is +1 means then the size of the image is equal to the size of the object.

What if magnification is less than 1?

A magnification of 1 (plus or minus) means that the image is the same size as the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object.

What is magnification of concave mirror?

The magnification m is given by m=−vu. 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.

Which of these can produce a magnification of 1?

both concave and plane mirror.

What is a magnification of 1?

Which can produce a magnification of 1 is?

Explanation: Plane mirror can produce a magnification of +1..

Why the magnification is +1 for a plane mirror?

The distance of object and distance of image are equal in the case of a plane mirror and the object distance is negative. Which gives us a magnification of +1.

Which mirror produces magnification less than 1?

In a concave mirror, magnification is equal to the negative of the ratio of the distance of the image from the mirror to the distance of the object from the mirror. So the given mirror must be a convex mirror as it always produces images smaller than the size of the object and its magnification is always less than 1.

Which lens has a magnification 1?

convex lens
The lens for which magnification can be 1 is convex lens. For this the object must be at 2F i.e.r at distance twice the focal length in front of the lens.

What is the magnification of a concave mirror?

In a concave mirror, the magnification is the ratio of the height of the image to the height of the object. The magnification is also equal to the negative of the ratio of the distance of the image from the mirror to the distance of the object from the mirror .

Why is the magnification of a plane mirror always 1?

Add your answer and earn points. The mirror must be a spherical mirror (concave mirror) as the magnification in plane mirror is never -1 but always 1. Also convex mirror always produces images smaller than the size of the object so it’s magnification is always less than 1.

What is the nature of image formed by a mirror?

Give the nature of image. The magnification of a mirror is -1. Hence, the image formed is real and inverted. This can be deduced from the formula, While considering image formation, h1 is always positive. So, this gives us h2 as negative. Hence, the image is real and inverted.

What is the meaning of negative magnification?

There could be two meaning of what you are asking. A magnification which is less than 1, i.e. Magnification usually meant that the size of image is greater than the size of object, so if the size of image is less than object then it can also be refer as negative magnification.
