Question

A wave of wavelength 0.60 cm is produced in air and it travels at a speed of 300 m/s. The

frequency of the wave is

(A) 20000 Hz
(B) 100000 Hz
(C) 50000 Hz
(D) 10000 Hz

Answer 1

50000 .Formula for finding frequency
frequency=velocity a wavelength
first convert cm to m
0.60/100=0.006
the f=300/0.006
300000/6

f= 50000hz
is it useful

Answer 2

50000 .Formula for finding frequency

frequency=velocity a wavelength

first convert cm to m

0.60/100=0.006

the f=300/0.006

300000/6

f= 50000hz
