A source S emitting sound of frequency 300Hz is fixed on block A which is attached to the free end of a spring SA as shown in figure. The dectector D fixed on block B attached to free end of spring SB detects this sound. The blocks A and B are simultaneously displaced towards each other through a distance of 1.0m and then left to vibrate. The maximum and minimum frequencies of sound detected by D, if the vibrational frequency of each block is 2Hz are Velocity of sound v =340m/s)
