The Concave Mirror Calculator is a powerful tool designed to determine the focal length of a concave mirror based on its radius of curvature. Understanding the focal length is crucial in optics, influencing the mirror's ability to converge light rays. This calculator simplifies a complex optical formula to make it accessible for anyone dealing with concave mirrors.
Formula of Concave Mirror Calculator
The calculator employs the following formula:
f = − (R/2)
Where:
- f is the focal length of the concave mirror.
- R is the radius of curvature of the concave mirror.
This concise formula encapsulates the relationship between the focal length and the mirror's curvature, providing a straightforward means of calculation.

Example of Concave Mirror Calculator
Let's illustrate the application of the Concave Mirror Calculator with an example:
Suppose we have a concave mirror with a radius of curvature (R) of 10 meters. Using the formula f =− (R / 2), we can calculate the focal length (f):
f = − (10 / 2) = −5 meters
Therefore, the focal length of the given concave mirror is 5 meters.
Most Common FAQs
A1: The negative focal length indicates that the concave mirror converges light rays, forming real images.
A2: No, this calculator is specifically designed for concave mirrors. The formula and principles differ for convex mirrors.
A3: A smaller radius of curvature leads to a more pronounced curvature, resulting in a shorter focal length and increased light convergence.
