The Mirror Equation Calculator is a helpful physics tool designed to calculate the object distance, image distance, or focal length of a mirror using the mirror equation 1f=1do+1di\frac{1}{f} = \frac{1}{dₒ} + \frac{1}{dᵢ}f1​=do​1​+di​1​. By entering any two known values, the calculator instantly finds the third parameter, making it easier to understand the behavior of concave and convex mirrors. This tool is perfect for students, teachers, and physics enthusiasts studying optics and image formation. Its clean design and instant results make it ideal for classroom use or embedding on educational websites.
