How does an oscillating charge radiate an electromagnetic wave ? Give the relation between the frequency of radiated wave and the frequency of oscillating charge. |
| Answer» SOLUTION :A charge Q OSCILLATING at a certain frequency produces an oscillating electric FIELD in space, which produces an oscillating magnetic field, which in turn is a source of oscillating electric field and so on. The oscillating electric and magnetic fields thus regenerate each other i.e., an electromagnetic wave PROPAGATES through the space. The frequency of the electromagnetic wave equals the frequency of oscillation of the charge. | |
