1. The problem statement, all variables and given/known data i'm doing a lab and i have a chart which requires me to find the wavelength. The chart looks like this: Frequency(f) Period (T) Length (l) Wavelength (lambda) 512 ? .15 ? 2. Relevant equations the equation is basically what im looking for 3. The attempt at a solution I think that L1=1/4 (lambda), and every time you go up a length is goes up (3/4, 5/4 etc.) Is this correct? Because then i could just sub in the length and solve for lambda.
