Definition: Electromagnetic tide or EM waves room waves that are developed as a an outcome of vibrations in between an electrical field and a magnetic field. In other words, EM waves space composed the oscillating magnetic and also electric fields.Description: Electromagnetic tide are formed when an electric field come in contact with a magnetic field. Lock are hence known as ‘electromagnetic’ waves. The electric field and also magnetic ar of one electromagnetic wave room perpendicular (at appropriate angles) to every other. Lock are likewise perpendicular to the direction the the EM wave. EM tide travel with a continuous velocity of 3.00 x 108 ms-1 in vacuum. They are deflected neither by the electrical field, no one by the magnetic field. However, castle are capable of showing interference or diffraction. One electromagnetic wave have the right to travel through anything - be it air, a solid product or vacuum. The does not need a medium to propagate or travel from one ar to another. Mechanically waves (like sound waves or water waves), on the various other hand, require a tool to travel. EM waves room "transverse" waves. This means that they room measured by their amplitude (height) and wavelength (distance in between the highest/lowest clues of two consecutive waves). The highest allude of a tide is well-known as "crest", conversely, the lowest suggest is known as "trough". Electromagnetic waves can be break-up into a range of frequencies. This is recognized as the electromagnetic spectrum. Instances of EM waves room radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
