Input interpretation
concave mirror image equations
Equation
1/i + 1/o = 1/f | M = -i/o | i | distance between image and mirror f | focal length o | distance between object and mirror M | subject magnification factor
Input values
focal length | 20 mm (millimeters) distance between object and mirror | 26 mm (millimeters)
Result
distance between image and mirror | 86.67 mm (millimeters) = 0.2843 feet = 3.412 inches = 8.667 cm (centimeters) = 0.08667 meters subject magnification factor | -3.333
