Answer :
The speed of wave on this rope is 15 n/m.
What is speed of wave in physics?
The speed of a wave, or any item besides, is the distance it voyages per unit of time. Speed is here and there alluded to as a proportion of how quick an item is moving. A quick wave has an enormous speed. Wave speed is the distance the wave goes in a given measure of time, for example, the quantity of meters it voyages each second. So in a period of one period, the wave has moved a distance of one frequency. Consolidating this data with the situation for speed (speed = distance/time), one might say that the speed of a wave is likewise the frequency/period.
