A string has a linear density of 6.2 x 10-3 kg/m and is under a tension of 250 N. The string is 1.2 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown in the drawing. Determine the (a) speed, (b) wavelength, and (c) frequency of the traveling waves that make up the standing wave.
I can't see your drawing but if there are no nods of standing wave between the ends
v = sqrt(T/m₀)
λ =v/f => f=v/ λ
