1.	Two tuning forks have frequencies 380 and 384 hz respectively . when they are sounded together then produce 4 beats after hearing the maximum sound how long will it take to hear the minimum sound
Answer» Beat PERIOD is GIVEN by T = 1/(f₁ - f₂) Given, f₁ = 384 Hz and f₂ = 380 So, T = 1/(384 - 380) = 1/4 sec ∵ time period between maximum and minimum sound = beat period/2 = (1/4 sec)/2 = 1/8 sec Hence, 1/8 sec will TAKE to hear the minimum sound = 1/8 sec
