Question

Sound wave travel with a certain speed, the wavelength
of sound is 0.5m whose frequency
is 600 Hz . Find the ware speed.​

Answer 1

V = f x λ
V = 600 x 0.5
V = 300 ms^-1

Answer 2

you can find your answer from this formula. anyway the answer is V=600Hz×0.5m

300

really, I didn't learnt about this formula. but it is also in my book. But haven't learnt till now
