Equation 4 given in the introduction is valid for any standing wave. Review the diagram in the apparatus section 2 and the generating standing waves section. Write a condition in the form of an equation that enforces the criteria of the fixed ends of the string.[1 Mark] . 2.) Rewrite the condition you found in the previous part to relate the wavelength to the length L. You should find that only certain values of are allowed, labeled by an integer n. [1 Mark] . 3.) In this lab, you will measure the frequency instead of wavelength. Write an equation relating frequency to wavelength and use it to eliminate from your equation. [1 Mark] 4.) The velocity of the wave on the string is given by: v = T / where v is the velocity of the wave, T is the tension in the string and is the linear mass density of the string (mass per unit length). Using this relationship and the results from the previous questions derive an equation relating the frequencies which lead to standing waves fn, the length of the string L, the hanging mass M, properties of the string, and the "standing
