Derivation of equation of travelling (progressive) wave | y(x,t) = A sin(kx - ωt + φ)

 

 

 In this video we derive equation of a Travelling (Progressive) Wave. 

 This step by step derivation will help all Class 11 physics students especially the meaning of Wave Number k and the meaning of Initial Wave conditions - initial phase angle.
