Electromagnetic Radiation and Energy(Planck's quantum theory)
where 'h' is proportionality constant, universally referred to as Planck's constant. It has a fixed value of: h = 6.63 x 10 3 4 joule.sec or h = 3.99 x 10 - 1 3 kJ sec mol - 1 . This relation was found to be valid for all types of electromagnetic radiation. The total amount of energy emit..
De-Broglie Relationship of freequency
Derivation of de-Broglie Relationship - The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of freque..

De-Broglie noted that according to the theory of relativity, the role played by momentum 'P' and the energy 'E' of the particle is done by angular frequency ' w ' and the propagation vector 'k' of a wav..
Temperature - Volume Relationship
If the pressure is kept constant, volume of a fixed mass of a gas increases with increase of temperature, measured on Kelvin or Absolute scale, and it decreases with the decrease in temperature. One litre of a gas at 273 K (Kelvin unit) will double in volume to 2 litres, if the temperature is dou..
Relationship between Electric Field and Potential
The above figure shows the electric field of a positive point charge. The electric field is directed away from the charge and potential is positive at any finite distance from the charge. If we move away from the charge, i.e., in the direction of the electric field we move ..
