Concave mirror distance, object distance, focal length online calculator

App Description

  1. First select the parameters to be calculated;

  2. Then fill in the other two parameters below;

  3. Click on "Calculate".

Calculation formula

\(1/u + 1/v = 1/f\)

u---object distance; v---image distance; f---focal length

Usage example

Input data:

Select calculated value: focal length

Image distance = 1; object distance = 1, click "Calculate"

Output results:

Focal length = 0.5.
