37 Results: The velocity of sound in air at room temperature __________ 0 C is v = _________________________________ m/ sec. Estimate the error in your determination of velocity of sound: V Emp (T) = V 0 T ; V 0 = at 20 0 or NTP Then calculate EMP V V Δ EMP V V = Δ ~ V tmp PART B 1. Sketch Lissajous pattern observed on the CRO screen for the phase differences of 0 0 , 90 0 , 180 0 , 270 0 between X and Y signals.
