Like the tailored fit, the modern fit also falls between a slim-fit and a traditional-fit dress shirt. An increasingly common term, vintage fit refers to a shirt that has the slim-cut shirt's narrow waist and smaller armholes but with a standard yoke.
The wave equation for a plane electric wave traveling in the x direction in space is. with the same form applying to the magnetic field wave in a plane perpendicular the electric field. Both the electric field and the magnetic field are perpendicular to the direction of travel x.
Electromagnetic energy is familiar to most people as light and heat, but it can take many other forms, such as radio waves and X-rays. These are all types of radiation originating from the electromagnetic force, which is responsible for all electrical and magnetic phenomena. The radiation travels at the speed of light in a manner resembling waves. Unlike sound waves, electromagnetic waves do not require a medium through which to move and can travel across empty space.
