What is magnification in mirror equation?

Study the following equation, called the “mirror magnification equation,” which relates the height of the image (H image), the height of the object (H object), D image and D object: M = H image/H object = – (D image/D object). Note the distance ratio is the same as the height ratio.

How do you calculate the magnification of a 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 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.

What is the formula for mirror?

The equation for image formation by rays near the optic axis of a mirror is called mirror formula/equation. Mirror Formula: 1/u + 1/v = 1/f.

What is the mirror equation?

Mirror formula is the relationship between object distance (u), image distance (v) and focal length. The mirror formula for concave mirror: 1/f=1/v+1/u.

What is the formula for a concave mirror?

The mirror formula for a concave mirror is given below. The magnification image formed by a spherical mirror is given by height of image divided by height of object. The formula is given as: \\(\\frac{1}{f}=\\frac{1}{v}+\\frac{1}{u}\\) Distances are to be measured from the pole (vertex) of the mirror marked by point V in the figure.

What is the formula for magnification?

The magnification formula is: M = H (i)/H (o) = -D (i)/D (o) In other words, the ratio of the image distance and object distance to the ratio of the image height and the object height.
