A scientist called De Broglie proposed that matterScience meaning: Matter is any substance (often a particle) that has mass, and also volume (occupies space). Matter exists in three states, solid, liquid and gas and is made up of... More can behave as wave as well as particles. He suggested that a particle of mass, m, moving with a velocity, v, would possess a wavelength λ, of
λ= \( \frac {h}{mv} = \frac{h}{p} \)
h – Plank’s constant
p – momentum p = mv
This wavelength is called De Broglie wavelength.
Plank’s Theory
This reveals that radiations are emitted in discrete packs or packets of energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More known as quanta.
E = hf
λ= \( \frac{hc}{\lambda} \)
c – Speed of light
h – Plank’s constant
f- frequency of radiation
λ = wavelength of radiation
