Compare calculators

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

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.

Critical Angle Calculator

Calculate the critical angle beyond which light undergoes total internal reflection at the boundary between a denser and a rarer medium. Essential for fiber optics, prism design, and understanding optical phenomena.
