Two sound waves of frequencies f1 = 400 Hz and f2 = 405 Hz are approaching an observer. Calculate the frequency of the beats perceived by this observer when the waves overlap and move away after approaching. Consider that the speed of sound in the air is 343 m/s and that the air temperature is adequate for the speed of sound to be constant.Answer sheet:
