Answer 1

Answer:

20hz to 2000hz is the audible range

Answer 2

Answer:22600 Hz and thus it won't be audible (ultrasonic sound as the frequency is more than 20000Hz)

Explanation:we know that..

Velocity = frequency × wavelength

Thus.,

339 = frequency ×1.5 ×10^-2 m

339÷1.5 ×10^-2 = frequency

On solving we get

Frequency = 22600 Hz
