Answer 1

Relation between speed of the sound (v) in the ar of the tube and temperature (T) of the tube is v (331.4+0.67) m/s Substitute given values -1331.4 +(0.6)(13°C)) m/s 342.2 mls Find wavelength v 342.2 mis -262 Hz. = 1.306 m As a both ends open organ pipe has anode in the middle, and two anti - nodes at each end, the length of the pipe 22 A.306m Part B Fundamental wavel enth 2L 1.306 m And fundamental frequency is 262 Hz Part C It is same as standing wave in tube 2, f-1.306 m, 262 Hz
