The length of an aluminum rod at 65°C if its length at 15°C is 1.2 meters is 1.201386 meters . Change in length = change in temp* length *coefficient of linear expansion of aluminium , coefficient of linear expansion of aluminium = 23 *10^6 degree C^-1 , change in length = 23 *10^6 * 1.2 * ( 65-15) , change in length = 1.2 * 23 *10^(6) * 50 = 0.00138 , Total length = 1.2 + 0.00138 = 1.20138 meter.

Suppose that during any period of ¼ second there is one instant at which the crests or troughs of component waves are exactly in phase and maximum reinforcement occurs. 4 beats will occur in 1 second.

Frequency or beats per second = 1/(1/4) = 4.
