1.	Beats are produced by two waves given by `y_1 = a sin2000 pit` and `y_2 =asin2008 pit`. The number of beats heard per second isA. zeroB. oneC. fourD. eight
Answer» Correct Answer - C Number of beats per second `=n_1-n_2` `omega_1=2000pi=2pin_1impliesn_1=1000` and `omega_2=2008pi=2pin_2impliesn_2=1004` Number of heats heard per sec`=1004-1000=4`
