Question

Sound produced by two vibrators have the same wavelength in two different gases to speed of the wave in two gases have 420 metre per second and 400 metre per second the vibrators when sounded together produced 8 beats per second find the frequencies of the two notes and the wavelength

Answer 1

Here,this is your answer.

I'm sure that it is absolutely correct.

Mark me as brainliest.i need it.

Answer 2

Answer:

Frequency (f) = 1 /Time (t)

f = 1 /1 = 1

Frequency of gases = 1Hz

Wavelength = velocity / frequency

wavelength = 420 ×1 = 420 lemda

Wavelength of both the gases is same as given that.

hope! it's right
