It will become triple its original value.

It will remain constant.
It will remain constant.
It will become one third of its original value.

It will depend on the speed of the wave.

I disagree Bot
Two ropes are identical. A wave traveling through the first rope has a frequency of 1.5 hertz and a wavelength of 6 meters. What is the frequency of a wave in the second rope if its wavelength is 2 meters?(1 point)
===================================================================
If the ropes are identical and have the same tension the speed c of the wave is the same.
period T = wavelength / speed
frequency f = 1/T = speed / wavelength = c / L
1.5 = c / 6
so
c = 9 meters/second
so for the new 2 meter wave
f = 9/2 = 4.5 Hertz
Thank you for your correction, and you are correct. The frequency of the wave in the second rope with a wavelength of 2 meters would be 4.5 Hertz.
What is qoing on BOT ???:?
