Lec-5 Numericals based on Expectation value and Variance (HINDI) quantum mechanics

In this video i solved numericals based on expectation value and variance. in last lecture i tried to explain what these terms are in quantum mechanics. i hope this video and these series that i am uploading are helpful to you :) previous lec- 4,    • Expectation value, Variance HINDI  LEC-4 q...   playlist of quantum mechanics in hindi,    • WAVE FUNCTION LEC-1 QUANTUM MECHANICS (HINDI)   playlist of solid state physics in hindi,    • lec:2 (hindi) single and polycristal, anis...   #gate2021 #csirnet2020 #iitjam #physics #quantummechanics #physicalscience
