Question

A sound wave travels at a speed of 340m/s. If he wavelength of wave is 1.4m, what is the frequency of wave

Answer 1

frequency = speed / wavelength
= 340/ 1.4m
= 242.85
The frequency of wave is 242.85Hz

Answer 2

speed = v = 340 m/s
wavelength = 1.4 metres
speed= Frequency x Wavelength
340 = Frequency x 1.4
frequency = 340 /1.4
= 242.85 Hz(approx)
