14PRACTICE PROBLEM
Two radio speakers are separated by 2.00 m. The speakers are playing a note of wavelength 68.6 cm that spreads evenly in all directions. A drone carrying a microphone orbits one of the speakers at a radius of 2.20 m. Determine all values of d less than or equal to 2.20 m measured from the other speaker for which the microphone will not detect any sound.
