How do you find the magnification of a convex mirror?

Expert Answer:

1. Magnification m = -v/u = 0.7.
2. where v is mirror to image distance and u is mirror to object distance .
3. we are given u = -30 cm ( Cartesian sign convention is applied)
4. hence , v = 0.7×30 = 21 cm.
5. we have mirror eqn., (1/v) + (1/u) = 1/f, where f is focal length.

What is the magnification produced by a convex mirror?

Magnification produced by convex mirror is always less than one and positive, since the image formed is always diminished and erect.

How do you prove magnification?

magnification=θ2qθ1p.

What is the formula for magnification of mirror?

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

What is the formula for magnification obtained with a mirror?

Ratio of height of image to height of object. Hence formula for Magnification is (M= v/u) .

What is M in convex 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.

Does the mirror equation work for a convex mirror?

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

Which of the following represents magnification M?

What is magnification in convex lens?

A convex lens can form virtual as well as real images, so the magnification produced by a convex lens can be either positive or negative. Magnification is positive for virtual image and negative for real image. When |m|>1, the image is magnified. When |m|=1, the image is of the same size as that of the object.

What is M in M v u?

m = -v/u. Where v is the image distance and u is the object distance.
