Some studies indicate that the upper fre- quency limit of hearing is determined by the diameter of the eardrum. The wavelength of the sound wave and the diameter of the eardrum are approximately equal at this up- per limit.
If this is so, what is the diameter of the eardrum of a person capable of hearing 2.0 × 104 Hz? Assume 337 m/s is the speed of sound in the ear.
Answer in units of m
