Will the frequency observed by a stationary observer will remain same if only the medium between the source and observer is moving?(ie. both source and observer are at rest and wind is blowing from source to the observer)
My textbook states that frequncy will not change and movembnt of medium will not haave any effect on frequency.
I think it is wrong. I think that initially it should change after that it would remain same.
My reason is that initially the travelling air (considered as medium) toward observer from source will increase the speed of waves in between source and observer after that the new waves will have changed wavelength ofsetting the change in velocity so the frequency will again become equal to the original.
Correct me if i am wrong, please.
$Any \ help\ is\ greatly\ appreciated$
