"hello everyone welcome to leader learning i am gurpreet your science tutor today's question is draw a curve showing density of pressure variations with respect to distance of a disturbance produced by the sun mark the position and compression of rear of compression and rear fraction on this curve also define wavelengths and the time period using the curve so here a figure is shown you can see this shows that density variation the first one then is your pressure variation and the curve which shows density of pressure variations with respect to the distance of a disturbance so here is a curve the distance between the two crest is known as the wavelength here right so this is the required figure for the answer for more such videos please subscribe leader learning and for any doubts drop a comment thank you"
