Image Formation in Plane and Curved Mirrors, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.
In daily life, magnification M is calculated by dividing the height of the image to the height of the original object. In symbols, we have:
However, applying the triangle similarity rules, we can use another formula for the magnification of curved mirrors. It considers the image and object's position and does not require any information about the height of the object. We have
If we consider the example in the previous paragraph, we obtain for the magnification of the concave mirror:
The above result means the image's height is triple the height of the original object. The sign minus indicates that the image is virtual.
