1. What is the equation for wavelength in terms of force?

2. What wavelength is required to get 5 standing wave segments on a doubly fixed string of length 0.75m? If the velocity v is 50m/s, what will be the frequency of this wave?

3. In stead drive one end of the string with a sinusoidal oscillator of frequency 100Hz. What velocity is required to setup a standing wave with 5 segments?
