Question

Speed of sound=339m/s
Wavelength=1.5m
Frequently=?

Answer 1

-----❤HEY MATE❤-----
HERE'S UR ANSWER

As per the wave equation
V= nu × lambda
i.e. V = wavelength × frequency
As per given condition
V= 339m/s
W= 1.5m
F=?
therefore,
339 = 1.5×F
339/1.5 = F
226 = F
therefore, frequency = 226 hz

Answer 2

V=f * wavelength

F= v/wavelength..

So, f=339/1.5

F=226 hz
