1. The problem statement, all variables and given/known data Two radio antennas transmit identical signals in phase and in all directions of frequency 120 MHz . The distance between the antennas is 8.95 m . Let the origin be at one antenna, and let x be a distance from the origin toward the other antenna. 2. Relevant equations Look at picture 3. The attempt at a solution Work done in attachment. I'm how to solve the problem. To get the maximum constructive interference, m and n would need to be whole number right? There are no whole number solutions to the equation I set up though.
