β Substances that absorb or emit light discontinuously in the form of small packets or bundles.
β The smallest packet of energy is called quantum (plural quanta).
β The radiation is propagated in the form of waves.
β The energy of a quantum is directly proportional to the frequency of the radiation

KEY NOTE
β Electric field at every point is normal to the equipotential
surface passing through that point.
β No work is required to move a test charge on unequipotential
surface.
β The electric force is conservative in nature.
β Coulomb force is central.
β In general, any non-conducting material can be called as a dielectric but broadly non-conducting material having non-polar molecules are referred to as dielectric.

PRINCIPLE OF HOMOGENEITY
β¨ The magnitude of a physical quantity may be added or subtracted from each other only if they have the same dimension, also the dimension on both sides of an equation must be same.This is called as principle of homogeneity.
β¨ Dimensional variables are those physical quantities which have dimensions and do not have fixed value.
β E.g., velocity, acceleration, force, work, power... etc.
β¨Dimensionless variables are those physical quantities which do not have dimensions and do not have fixed value.,
β E.g., Specific gravity, refractive index, Coefficient of friction, Poissonβs Ratio etc.,
