Answer Text:
Planck’s constant
-When a bunch of oscillating atoms and the energy of each oscillating atom is quantified i.e. it could only take discrete values. Max Planck’s
predicted the energy of an oscillating atom to be E = n h f, where n – integer, f
– frequency of the source, h – Planck’s constant which has a value of #6.63 × 10^-34# Js.
