4 days ago · Ground waves are radio waves that travel or propagate along the surface of the earth. These radio waves induce a current in the ground from which they pass. While propagating through the medium waves will have losses as well as absorption. Therefore there will be a loss of signal or power. The more the frequency of waves the more will be losses.
4 days ago · Radiation - Cancer Treatment, Ionizing Radiation, Disease: In addition to X rays and gamma rays, densely ionizing particles—neutrons, protons, mesons, alpha particles, and heavy ions, for example—have been used increasingly to treat cancer and other lesions. Such high-LET radiations (see above The passage of matter rays: Linear energy transfer and track structure) offer potential ...
Jun 28, 2024 · The electromagnetic waves that are used in a remote controller are called radio waves. The radio waves have wavelengths ranging from 1 mm (i.e. shorter than a grain of rice) to 10,000 km (i.e. longer than the radius of our earth). Now, we can imagine how long the wavelength of a radio wave can be. These waves are invisible to a human eye.
3 days ago · A plane electromagnetic wave travels in free space. Then the ratio of the magnitude of electric and magnetic field at a point is equal to: A. Inverse of the velocity of the electromagnetic wave B. Inverse of the energy of electromagnetic wave C. Velocity of electromagnetic waves. D. Energy of electromagnetic waves.
4 days ago · The instantaneous electromagnetic wave intensity of a uniform plane wave. Thus Poynting’s theorem says that the integral of the inward component of the Poynting overlinetor over the surface of any volume V equals the sum of the power dissipated and the rate of energy storage increase inside that volume.
3 days ago · EM waves propagate in a direction that is perpendicular to its electromagnetic oscillations and are hence termed to be transverse waves. Classically, EM waves are emitted from a point source and thus form a spherical wave front. Together, all EM waves form an EM spectrum that encompasses all EM radiation that we know of.
4 days ago · Electromagnetic waves also are referred to as EM waves that are produced when an electrical field comes in touch with the magnetic flux. It can also be said that electromagnetic waves are the composition of oscillating electric and magnetic fields. Applications of Electromagnetic Waves Following are a few applications of electromagnetic waves: 1.
