A 1.30-m string of weight 0.0125 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Neglect the v
ery small variation in tension along the length of the string that is produced by the weight of the string. When you pluck the string slightly, the waves traveling up the string obey the equationy(x,t)=(8.50mm)cos(172rad⋅m−1x−2730rad⋅s−1t)Assume that the tension of the string is constant and equal to W.How much time does it take a pulse to travel the full length of the string?What was the weight W?How many wavelengths are on the string at any instant of time?What is the equation for waves traveling down the string?
A waves frequency (in Hertz) is how many crests pass by a point per second. easily confused with period, which is the amount of time it takes for a full wave to pass by a certain point
