The field of optics studies the properties and behaviors of light. This includes the interactions of absorption, emission, reflection, refraction and diffraction. Use Wolfram|Alpha to compute properties of these phenomena. Learn about atomic spectral lines and lasers or calculate important measurements in photography.
Compute total internal reflection, Fresnel's law or the plate reflectance of a Fabry–Pérot interferometer.
Compute diffraction patterns for a large range of diffraction obstacles, including single slits, double slits and more.
Find the visible spectrum of different substances. Obtain initial and final atomic states for different lines.
Compute refractive indices, refractions using Snell's law or the position of rainbows.
Get information on different types of lasers and their properties. Examine their frequencies and colors.
Compute field of view, f-stop, depth of field, focal length and more.
