A rope is vibrating at high frequency. The length of the rope is 2.40 meters. A snapshot of the rope at a given moment in time is also shown. Use this information to determine the
wavelength of the wave.

λ = L / # _ periods

Explanation:

We don't have the image of the string, but a wavelength is the minimum distance when the wave repeats, therefore the distance between two consecutive maxima is the wavelength in the string

A method used to decrease the error is to measure the distance in several consecutive maxima and divide the number of them, in this way the error in the measurements is divided between all the points, so the value of the wavelength is more exact

               λ = L / # _ periods

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
