string at a speed of 3 m/s.? The period of the wave is 0.23 seconds and the amplitude is 0.5 m.
a) What is the wavelength if these waves generated on the string?
b) How many wavelengths are contained within a 5 m portion of the string?
c) What new wave speed would generate a n=4 standing wave if a 5 m portion of this string is fixed at both ends?

Need help on how to find these and what equations to use. Thank you!!
