Define Planck equation
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu:
E = h nu.
Ergosphere: The area around a rotating black hole, among the event horizon and the static limit, where the rotational energy can be removed from the black hole.
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 is main difference between secondary electron image and the back scattered electron image? State briefly.
Hooke's law (R. Hooke): The stress exerted to any solid is proportional to the strain it generates within the elastic limit for that solid. The constant of that proportionality is the Young modulus of elasticity for that material.
Rayleigh-Jeans law: For a blackbody at the thermodynamic temperature T, the radiance R over a range of frequencies between the nu and nu + dnu is specified by: R = 2 pi nu2 k T/c2.<
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Cadmium rods are given in a nuclear reactor. Explain why?
Occam's [or Ockham's] razor (William of Occam [or Ockham]; c. 1340): It is the suggestion that the simpler a theory is the better. When two theories forecast the phenomena to the similar accuracy, then the one that is simpler is the better one. Furthe
