Object Distance in Concave Lens Solution

STEP 0: Pre-Calculation Summary

Formula Used

Object Distance = (Image Distance*Focal Length of Concave Lens)/(Focal Length of Concave Lens-Image Distance)
u = (v*F_{concave lens})/(F_{concave lens}-v)
This formula uses 3 Variables

Variables Used

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.
Focal Length of Concave Lens - (Measured in Meter) - Focal Length of Concave Lens is a measure of how strongly the lens diverges light.

STEP 1: Convert Input(s) to Base Unit

Image Distance: 0.27 Meter --> 0.27 Meter No Conversion Required
Focal Length of Concave Lens: -0.45 Meter --> -0.45 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

u = (v*F_{concave lens})/(F_{concave lens}-v) --> (0.27*(-0.45))/((-0.45)-0.27)

Evaluating ... ...

u = 0.16875

STEP 3: Convert Result to Output's Unit

0.16875 Meter --> No Conversion Required

FINAL ANSWER

0.16875 Meter <-- Object Distance

What is Concave Lens?

As the parallel rays converge, the convex lens is termed as a converging lens. Similarly, a concave lens is called diverging lenses because they cause parallel rays to diverge. The convex lens is curved towards the inside. The concave lens is curved towards the outside.
