Ally conducts a physics experiment to determine the speed of sound in air. Using the resonance set up as shown in fig. She uses a tuning fork of frequency 388 Hz and determines the first resonating length of the air column to be 0.22 m. Determine the temperature of air in the room. (speed of sound in air at 0° C = 331m/s; it increases by 0.6 m/s for every1° C rise in temperature).
