Quantum Theory of Light:
Wave theory failed to describe some new effects in 19th century. A German Physicist Max Plank gave theory about the nature of light.
1. Light is emitted from a source in tiny packets of energy or Quanta.
2. These energy packets or bundles of light known as Photon.
3.The light is emitted and absorbed in the form of Photons.
4.The energy possessed by a photon depends upon its frequency
First law of thermodynamics is stand on the principle of the conservation of power. According to the first law, ΔQ = W + ΔU Where, Δ Q = heat given to the system
Define Adiabatic Atmospheres (Boston, Maryland)? The lower 10-15 km of the troposphere, the atmosphere, is often in a convective stable state with constant entropy, not constan
Color vision and chromatic aberration: One of the remarkable ability of the eye is its ability to see color. There are three types of cones that respond to light from three
what are solid core fibres?
Which is factual of the light from an actual physical object whose image is formed by a single thin lens? Ans: That's what light perform when it leaves a point on an objec
The phase of weightlessness may be observed in the following situations: (i) When objects fall freely under gravity : For example, a lift goes down freely, or an airship showing
Gauss' law for magnetic fields The magnetic flux by a closed surface is zero; no magnetic charges present. In differential form, div B = 0.
Core losses or Iron losses: These losses having of hysteresis and eddy current losses, which happen due to pulsation of flux in the core. These losses depend upon the maximum flux
