A point like sound source emits sound in all direction uniformly. An observer who is at a distance of 50m from the source detects sound of intensity 10−8 watt /m2. If the bulk modulus of air is 1.6×105N∕m2 and velocity of sound is 340m∕s. Find pressure amplitude at the position of observer. If your answer is x×10−3N∕m2 fill value of [x]
