Q. Two sound sources radiating in phase at a frequency of 560 Hz interfere such that maxima are heard at angles of 0 and 25° from a line perpendicular to that joining the two sources. Find the separation between the two sources. (Wave velocity of sound is 340 m/s)
Q. A 8 m long string, clamped at both ends, vibrates at 52 Hz. If the string resonates in 6 segments, what is the speed of transverse waves on the string?
