A certain dog whistle operates at 23,5khz, while another brandX operates at an unknown frequency. If neither whistle can be heard by humans when played seperately but a shrill whine of frequency 5kHz occurs when they are play simultaneously, estimate the operating frequency of brand X.
do i have to subtract the 23.5k from 5 to find its difference? Since beat frequency = differ in the 2 wave frequncies or what? I am confused with what to do?
Thanks!
