Expert Answer
If the original periodic sound coincides with the reflected sound from wall,
then we have , 2d/T = speed-of-sound .......................(1)
where d is distance between source of sound and wall, T is time period between successive sound pulse
if 100 claps per minute means, time period T = (1/100) min = (60/100) s = 0.6 s
from eqn. (1), 2d/(0.6) = 330 or d = 330 × 0.3 = 99 m
