Two identical stretched wires are vibrated together. They produce 8 beats per second. When tension in one wire is changed then the beat frequency is increased. If T1 and T2 denote the tensions in the two wires at any instant and T1 > T2 (initially) then how the change may be performed.

In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1 m. When this length is changed to 0.35 m, the same tuning fork resonates with the first overtone. Calculate the end correction :
