$begingroup$ Whether it''s "light" or "radio", electromagnetic radiation can be studied using either the classical theory (waves) or the quantum theory (photons). Like in many areas of physics, the classical theory is good enough for most things, but the quantum theory is needed to understand some observations that aren''t explained by the ...
In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields. (See Figure 1.) Thus the energy carried and the intensity I of an electromagnetic wave is proportional to E 2 and B 2. In fact, for a continuous sinusoidal electromagnetic wave, the average intensity I ave is given by
Energy will also be lost due to electromagnetic radiation. The amount of energy loss depends on the size of the circuitry. In the limit of infinitely small inductors and capacitors the loss to radiation falls to zero. In general, you want the …
Energy carried by a wave is proportional to its amplitude squared. With electromagnetic waves, larger E-fields and B-fields exert larger forces and can do more work. But there is energy in an electromagnetic wave, whether it is absorbed or not. Once created, the …
Electromagnetic waves are produced by the motion of a dipole and suppose we have top and bottom points then the negative and positive charges must oscillate between those 2 points. However an LC oscillator does exactly the same thing if you consider the poles to be each conductive plate of the capacitor.

Maxwell argued that a changing electric field between the capacitor plates must induce a magnetic field. As currents are the usual sources of magnetic fields, a changing electric field must be associated with a current. ... When an object bums, it emits colours. That is, it emits electromagnetic radiation which depends on temperature. If the ...
