The smallest unit of energy is the Planck. This unit of energy is named after Max Planck and is in the natural system of energy.
The smallest unit of sound wave energy is the phonon. The phonon and the photon and the electron can in some ways all behave like a small particle.
If the photon is having very less frequency (say v=1Hz) ,then the Energy of such photon will be the smallest one. It can be inferred that the smallest unit of light energy will correspond to the smallest frequency of such quanta. But from the uncertainty principle it limits the energy of a quanta.
No. A quantum is a small and indivisible unit of SOMETHING, which might be energy, charge, spin, or several other things.
The quantum of light energy is called a photon. It is the smallest possible discrete unit of light.
An atom is the smallest unit of matter that retains the properties of an element.
The chlorophyll on exposure to light energy becomes activated by absorbing photons(photon is the smallest unit of light energy)
The smallest unit is a quark. I'm not sure what you mean by 'of classification'
If it is a molecular compound, the smallest unit is called a molecule. If it is an ionic compound, the smallest unit is called a formula unit.
Alyssa Carney is the smallest unit of mass.
A molecule is a compounds smallest unit
This smallest unit is the atom.
A cell is the smallest unit of an organism
