1. The problem statement, all variables and given/known data Initially your receiver is positioned at a distance of 8.4 cm from the goniometer and recording a maximum intensity. You move it through 10 minimums in the intensity and then stop at the next maximum intensity. The receiver is now a distance of 27.3 cm from the goniometer. What is the wavelength of the signal you have measured? 2. Relevant equations ƛ/2=Distance between two maximums 3. The attempt at a solution ƛ=2(27.3-8.4)cm =37.8cm It's that simple right? I keep getting the wrong answer with this. What am I missing?
