What is the Object Distance Calculator?

The Object Distance Calculator helps students, photographers, and optics enthusiasts determine the position of an object in relation to a lens using the lens formula. By entering the focal length and the image distance, the tool calculates the object distance accurately. This is useful in designing optical systems, understanding lens behavior, and performing practical experiments in physics and photography.

How to Use:

1. Enter Focal Length (f) in cm: Input the focal length of the lens.
2. Enter Image Distance (v) in cm: Input the distance from the lens to the image formed.
3. Click “Calculate”: The tool computes the object distance using the lens formula.
4. Review Result: The output displays the entered focal length and image distance, the calculated object distance (u) in cm, and the formula used: 1/f = 1/v + 1/u.
