Can magnification of concave mirror be positive?

Can magnification of concave mirror be positive?

Use the mirror equation to deduce that: (a) an object placed between f and 2f of a concave mirror produces a real image beyond 2f. (c) the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole.

When the image is real and inverted the magnification of mirror is?

For a real and inverted image, the height of the image is negative and the height of the object is positive. So the magnification of the mirror is negative.

Is the magnification of a concave mirror positive or 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.

Can a concave mirror produce an inverted image?

Reflection from a Concave Mirror When the object is far from the mirror, the image is inverted and at the focal point. The image is real light rays actually focus at the image location).

In which case magnification is positive?

(a) The magnification is positive for all virtual images and is negative for all real images. (b) The magnification of concave lens and convex mirror is always positive where as the magnification of convex lens and concave mirror can be positive or negative depending on the position of the object before the lens.

Why magnification of convex mirror is positive?

The sign of magnification depend on the sign convention chosen. According to the new Cartesian sign conventions, magnification for a convex mirror is positive because image formed by a convex mirror is always virtual and erect. A concave mirror can form virtual or erect images and also real, inverted images.

When the magnification is negative the image formed by a concave mirror must be real and inverted?

If the magnification has a negative sign, the image formed by the concave mirror must be. Real and Inverted. Virtual and Erect. Real and Erect.

When an inverted image can be seen in a convex mirror?

when the object is at a distance equal to the radius of curvature of the mirror.

What Cannot be the magnification of concave mirror?

Note: 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.

Why is the magnification of a real image negative?

A negative magnification indicates that the image is inverted. If the object is placed closer to a converging lens than the focal length, the rays on the far side of the lens diverge. The virtual image is upright and the magnification is positive in this case.

Is concave mirror upright or inverted?

A plane mirror will always produce an upright image. A concave mirror will only produce an upright image if the object is located in front of the focal point.

Why is the magnification of a concave mirror negative?

Negative magnification means that the image formed by a spherical mirror is real and inverted. Also, why focal length of concave mirror is negative? f, the focal length, is positive for a concave mirror, and negative for a convex mirror.

What is the magnification of an inverted image with m=2?

An inverted image is magnified by 2 when the object is placed 22 cm in front of a concave mirror. Determine the image distance and the focal length of the mirror. If M=2 and the image is inverted, then the d i must be +44 cm. (It isn’t -44 cm since the negative sign would only correspond to an upright and virtual image.)

What does it mean when the magnification is negative?

When the image distance is negative, the image is behind the mirror, so the image is virtual and upright. A negative m means that the image is inverted. Positive means an upright image. Furthermore, what is a negative magnification? A negative magnification indicates that the image is inverted.

What are the sign conventions for magnification and mirror equation?

The sign conventions for the given quantities in the mirror equation and magnification equations are as follows: d i is + if the image is a real image and located on the object’s side of the mirror. d i is – if the image is a virtual image and located behind the mirror.
