Answer 2

Answer:

1)-200hz

2)-0.005s

Explanation:

1)

wave velocity = 340m/s

wavelength. = 1.7m

frequency = ?

wave velocity = wavelength × frequency

frequency = wave velocity /wavelength

frequency = 340/1.7

frequency = 200Hz

2)

time period = 1/frequency

time period =1/200

time period = 0.005s
