Expert Answer
(1) Velocity of sound is independent of pressure if temperature is kept constant. Hence graph-(A) is not correct
(2) Velocity v of sound is proportional to square root of temperature T. v 
√T or v2 T
√T or v2 T(3) Velocity v of transverse wave in string = 
, where T is tension in the string and μ is linear mass density of string.
, where T is tension in the string and μ is linear mass density of string.hence v √T or v2 T . Hence graph(C) is correct
√T or v2 T . Hence graph(C) is correct(4) for fundamental mode, wavelength λ of open end organ pipe is given by λ = 2L , where L is length of pipe.
hence if v is velocity of sound in air, frequency f = v/λ = v/(2L). hence f 1/L
1/L if graph(D) is showing inverse function, then graph(D) is correct
