In first and second case observer was moving but in this case source is moving..in first and second case we find relative velocity but in 3rd case we are saying thats not having relative motion..smjh ni aya ye point..in these all point one substance is moving..then
when source at rest it produce sound waves in air right bt when observer move towards source sound waves show also compression bt we talk jst about speed can we talk about wavelength in that case?
the way of your teaching is very impressive sir g thank you sir g
Sir ya bht mushkil lagta tha but atna easy ha mujhe aj pata chala thanx my favrt teacher
Awsm vdo well done sir keep it up
MashAllah sir keep it up

Please answer Sir
Sir when both are moving than...?
Sir smj nahi aya. !.
Yeh sab smj agaya k wavelength change ho raha hai etc.
Isko ap compare kar k parhaty toh ziada achay se smj atha.
