Quantum Mechanics

De Broglie Wavelength Calculator

$begin mathsize 36px style lambda equals fraction numerator h over denominator m. v end fraction end style$

λ= De Broglie Wavelength ; m= mass ; v= velocity ; h = Plank's constant ( 6.6262 x 10^-34 Js)

Compton Scattering Caculator

$begin mathsize 36px style lambda minus lambda apostrophe space equals space fraction numerator h over denominator m subscript e c end fraction open parentheses 1 minus space cos theta space close parentheses end style$

λ= Initial wavelength of the photon before scattering; λ' = Final wavelength of the photon after scattering; θ = Scattering angle; h= Plank's constant ; m_e = Rest mass of an electron; c = speed of light in vaccum

Particle in a 1D Box Calculator

$begin mathsize 36px style E equals fraction numerator n squared h squared over denominator 8 m L squared end fraction end style$

E= Energy at the n^th state; n = quantum number ; h= Plank's constant ; m = mass of the particle; L= Box length
