In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

In physics, Maxwell's equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. They underpin all electric, optical and radio such electromagnetic technologies as power generation, electric motors, wireless communication, cameras, televisions, computers, and radar. Maxwell's equations describe how electric and magnetic fields are generated by charges, currents, and changes of these fields. The equations have two major variants. The microscopic Maxwell equations have universal applicability but are unwieldy for common calculations. They relate the electric and magnetic fields to total charge and total current, including the complicated charges and currents in materials at the atomic scale. The macroscopic Maxwell equations define two new auxiliary fields that describe the large-scale behaviour of matter without having to consider atomic scale details. The equations were published by Maxwell in his 1864 paper "A Dynamical Theory of the Electromagnetic Field". In the original paper Maxwell fully derived them from the Lorentz force law (without using the Lorentz transformation) and also from the conservation of energy and momentum.

here. In this problem we have to find new frequency when tension indiscretion is increased by 15%. Suppose initially tension is Stephen and after attention ISTEA too. So we can write tension. T two is 15% increased. That means it is 1.15 off Stephen. No, we knew that frequency F is equal toe the y lambda and we know that it's feared V is equal to under rupee by mu so we can write Frequency is equal to went up on Linda under rude de vie view So suppose initially frequency is effort and after frequencies have to So we can write after why everyone should be equal Toe one upon Lambda Stephen D To buy Mu in one upon Lambda F one is equal toe even by mu Since Mu and Lambda is same so we can write f toe by f one will be equal toe under road T two way Even so, we can write the frequency will be equal to f front in tow, under duty to write Even we knew that initial frequency is given which is to 94 hers multiple life t to fight even we know that the to write even should be equal to one point 15 So the new frequency will be equal to. After calculating this, we get 31 500. This is the new frequency. Yeah.
