How radiation emitted from the body
Describe the procedure how radiation emitted from the body? Illustrate in brief.
Expert
The body radiates energy via thermal conduction via the skin to the air, clothes, and so on around the body. The small amount of energy would as well be radiated as electromagnetic radiation with the peak wavelength directly associated to the Kelvin temperature of skin.

Tachyon: The purely speculative particle that is supposed to travel faster than light. According to Sir Einstein's equations of special relativity, a particle with imaginary rest mass and a velocity more than c would contain a real momentum and energy
Superconductivity: The phenomenon by which, at adequately low temperatures, a conductor can conduct the charge with zero (0) resistance. The current theory for describing superconductivity is the BCS theory.
What does MeV in MeV photon signify? Briefly describe it.
Bernoulli's equation - In an ir-rotational fluid, the sum of static pressure, the weight of the fluid per unit mass times the height and half of the density times the velocity squared is steady all through the fluid
Brewster's law (D. Brewster) - The extent or level of the polarization of light reflected from a transparent surface is maximum whenever the reflected ray is at right angle to the refracted ray.
