ENERGY LEVELS
The energy levels, measured in electron volts (e.v.) in which orbiting electrons exist comply with a law of physics which states that energy can be given to electrons only in discrete amounts (quanta) which means that there are energy values that an electron cannot acquire. From this it can be deducted that there is a forbidden energy gap between each of the allowed energy bands K to O.
The width of the forbidden energy gap between the top of the valence band and the bottom of the conduction band determine the electrical conducting properties of materials.
Illustrates the formula of Rayleigh-jeans law? RAYLEIGH-JEANS LAW The energy distribution into the thermal spectrum is specified by given formula as follows: E λ = 8Πk
An isotope of iodine (Z = 53) is used to treat thyroid conditions. Its mass number is 131. How many neutrons are in its nucleus? 131 - 53 = 78 neutrons
Working of nicol prism and its uses as polarizer and analyzer
how nicol prism is constructed?
Could the light along a side emitting optic be a totally homogeneous? Regardless of the assurances of several manufacturers, it is a total impossibility since it would clash wi
What is a hypothesis for a Hooke''s Law experiment which was completed with a single, series and parallel spring arrangement?
the two point charges +10 nano coulomb and -20 nano coulomb are seperated by a distance 0.1m. calculate the neutral poiint along the line joining two charges.
In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0). Thus from first law of thermodynam
Dispersion of Light: When a beam of light is permitted to pass by a prism, it splits in a band of different colors. This band of different colors is known as spectrum and the p
