Question

What is quanta?

Answer 1

Quanta

• A quantum (quanta is the plural) is the smallest possible unit of something, usually energy.
• It is considered to be the discrete packets with the energy stored in them.
• It refers to the minimum amount of energy required for a change or the minimum value of any physical property in an interaction
• In Max Plank's discovery of quanta, it is given as energy with an equation of $E=hv$
• In the photoelectric effect, Albert Einstein postulated that light was emitted and absorbed as localized packets or quanta (now called photons)
• For example, you can't have an infinitely small amount of light. You can have, at the very minimum, one quantum of light.
