A string has a linear density of 6.1 x 10-3 kg/m and is under a tension of 340 N. The string is 1.4 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 figure out the speed but I can't figure out the wavelength with out the frequency and vice versa
