quantum theory experiments

In 1900, Max Planck presented the results of his famous black body radiation experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the Quantum Theory of Radiation explaining electromagnetic radiation and en..

According to Max Planck's Quantum theory, radiation is not continuous but is made up of tiny packets of energy called photons. However, this theory could not explain other optical phenomena. From all the above theories it is clear that certain optical phenome..

Quantum Theory of Covalent Bond - Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the..

Two new theories came to substantially modify Bohr's Atomic model. They a..

John Dalton, a British school teacher, published his theory about atoms in the year 1808. His findings were based on experiments and also from laws of chemical combinatio..

Origin of Surface Tension (Molecular Theory)..

In experiments on pea breeding, Mendel obtained the following frequencies of seeds: 315 round and yellow, 101 wrinkled and yellow, 108 round and green, 32 wrinkled and green. Theory predicts that the frequencies should be in the ratio 9 : 3 : 3 : 1. At α = 0.01, find chi-s..
