Diffraction gratings are powerful optical devices used to separate and analyze light into its component wavelengths. Unlike a double-slit arrangement that only involves two slits, a diffraction grating consists of many equally spaced slits (or rulings), often several hundred to thousands per millimeter.
Kepler’s Laws are one of the most tested topics in orbital mechanics. This guide will help you understand all 3 powerful laws with formulas and exam-style examples.
Why do planets speed up near the Sun and slow down when they are far away?
The answers live in Kepler’s laws, elegantly explained today using Newtonian mechanics. This article walks you through the ideas, the math, and a couple of quick examples you can use right away.
Newton’s inverse–square law predicts that a spherical body attracts an external particle as if all its mass were concentrated at the center.
This is not obvious: different surface elements pull in different directions. The justification requires a calculus argument, which integrates the contributions of infinitesimal mass elements on a spherical shell.
