The Wien's displacement law express relation between
- wavelength corresponding to maximum energy and temperature
- radiation energy and wavelength
- temperature and wavelength
- colour of light and temperature
The Correct Option is A
Solution and Explanation
Wien's displacement law states that the product of absolute temperature and the
wavelength at which the emissive power is maximum is constant i.e. \(\lambda _{max} \,T\) = constant
Therefore it expresses relation between wavelength corresponding to maximum energy
and temperature.

Concepts Used:
Conductance
What is conductance?
Conductance is an expression of the ease with which electric current flows through materials like metals and nonmetals. In equations, an uppercase letter G symbolizes conductance. The standard unit of conductance is siemens (S), formerly known as mho.
What is conductance in electricity?
Conductance in electricity is considered the opposite of resistance (R). Resistance is essentially the amount of friction a component presents to the flow of current.
The conductivity of electrolytic solutions is governed by the following factors:
- Interionic attraction
- Solvation of ions
- The viscosity of the solvent
- Temperature
