Focal Length of Convex Mirror Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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

Evaluating ... ...

F_convex = -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 Convex Mirror
