A string has a linear density of 6.7 x 10-3 kg/m and is under a tension of 210 N. The string is 1.6 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.
In the diagram, there are 2 nodes and 3 half wave cycles. I only need help with b and c.
The distance between nodes is 1/2 wavelength.
if you have speed, frequency(wavelength)=speed
