It was noted pretty early on in physics that in simple collisions, two quantities mass*velocity and 1/2 * mass* velocity 2 stayed the same which made them easy to use- one was called "momentum" and the other "kinetic energy". It was observed that the speed of an object (and so it's kinetic energy ... Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both … Meer weergeven Microwaves travel solely by line-of-sight paths; unlike lower frequency radio waves, they do not travel as ground waves which follow the contour of the Earth, or reflect off the ionosphere (skywaves).
