Concave Mirror Equation Calculator

A mirror that has been curved towards inward in the middle is known as ‘Concave Mirror’. Mirror equation is the equation deals with concave mirrors. It has the the relationship between the object distance (do), the image distance (di), and the focal length (f). Use this concave mirror equation calculator to calculate the mirror equation. You can also choose the drop down list given in this calculator to calculate image distance, object distance and focal length.

Calculate Focal Length, Image and Object Distance

Example:

Calculate focal length (f) of an object having a image distance of 5 and object distance of 7.

Solution:

Concave Mirror Equation = (1/5) + (1/7)
= 2.91
