can someone check my work??
You and a friend are each holding an end of a string. Together you make a standing wave. If the wavelength is 3m, what is the closest distance you and your friend can be to each other? What is the velocity of this wave if the frequency is 200Hz? What is the tension in the string if it has a linear mass density of 2 kg/m?
