High frequency alternating current by a loud speaker, Physics

Assignment Help:

Give reason that ultrasonics not be produced by passing high frequency alternating current by a loud speaker

At these high frequencies, inductive reactance is so high where is no current flows throughout the coil of the loud speaker and therefore ultrasonic waves cannot be produced.
