Directly proportional
Physics; General physics
Two quantities are directly proportional if an increase in one results in a proportional increase in the other, and a decrease in one results in a proportional decrease in the other. In a formula ...
Diffraction grating
Physics; General physics
A sheet, film, or screen with a pattern of equally spaced slits. Typically the width of the slits and space between them is chosen to generate a particular diffraction pattern.
Dynamics
Physics; General physics
The application of kinematics to understand why objects move the way they do. More precisely, dynamics is the study of how forces cause motion.
Electromagnetic spectrum
Physics; General physics
The spectrum containing all the different kinds of electromagnetic waves, ranging in wavelength and frequency.
Efficiency
Physics; General physics
For a heat engine, the ratio of work done by the engine to heat intake. Efficiency is never 100%.
Elastic collision
Physics; General physics
A collision in which both kinetic energy and momentum are conserved.
