Focal Length of Concave Mirror with Virtual Image Solution

STEP 0: Pre-Calculation Summary

Formula Used

Focal Length of Concave Mirror = (Image Distance*Object Distance)/(Object Distance-Image Distance)
F_concave = (v*u)/(u-v)
This formula uses 3 Variables

Variables Used

Focal Length of Concave Mirror - (Measured in Meter) - Focal Length of Concave Mirror is a measure of how strongly the mirror diverges or converges light.
Image Distance - (Measured in Meter) - Image Distance is the distance of the image from the lens or the mirror.
Object Distance - (Measured in Meter) - Object Distance is the distance of the object from the mirror.

STEP 1: Convert Input(s) to Base Unit

Image Distance: 0.27 Meter --> 0.27 Meter No Conversion Required
Object Distance: 0.9 Meter --> 0.9 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_concave = (v*u)/(u-v) --> (0.27*0.9)/(0.9-0.27)

Evaluating ... ...

F_concave = 0.385714285714286

STEP 3: Convert Result to Output's Unit

0.385714285714286 Meter --> No Conversion Required

FINAL ANSWER

0.385714285714286 ≈ 0.385714 Meter <-- Focal Length of Concave Mirror
