Electromagnetic radiation and B fields in EMR are in-phase (see math section below). An important aspect of light's nature is its frequency. The frequency of a wave is its rate of oscillation and is measured in hertz, the SI unit of frequency, where one hertz is equal to one oscillation per second. Light usually has multiple frequencies that sum to form the resultant wave. Different frequencies undergo different angles of refraction, a phenomenon known as dispersion. A wave consists of successive troughs and crests, and the distance between two adjacent crests or troughs is called the wavelength. Waves of the electromagnetic spectrum
Distance between two straight lines equations of two non-vertical parallel lines the distance between the two lines is the distance between the two intersection points of these lines with the perpendicular line This distance can be found by first solving the linear systems and to get the coordinates of the intersection points. The solutions to the linear systems are the points and The distance between the points is which reduces to When the lines are given by the distance between them can be expressed as Distance between two straight lines The distance between two straight lines in the plane is the minimum distance between any
