Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Snell's Law Calculator

Determine the refraction angle when light passes between two media of different refractive indices using Snell's Law. Useful in optics coursework, lens design, and understanding phenomena like rainbows and fiber optics.

Magnification Calculator

Compute the optical magnification of a lens or mirror by comparing the image height to the object height. Use it to determine whether a lens enlarges, reduces, or inverts an object.

Image Height (cm)

Object Height (cm)
