1.	A cylinder ABC consists of two chambers 1 and 2 which contains two different gases. The wall C is rigid but the walls A and B are thin diaphragms. A vibrating tuning fork approaches the wall A with velocity u = 30 m//s and air column in chamber 1 and 2 vibrates with minimum frequency such that there is node (displacement) at B and antinode (displacement) at A. Find : (i) the fundamental frequency of air column (ii) find the frequency of tuning fork. Assume velocity of sound in the first and second chamber be 1100 m/s and 300 m/s respectively. .
