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.

Note

The imaging of concave mirror is related to image distance, object distance and focal length
