Two radio antennas A and B radiate in phase at a frequency of 15 MHz. Antenna B is 120 m to the right of antenna A. Consider point Q along the line connecting the antennas, a horizontal distance x to the right of antenna A. The frequency, and hence the wavelength, of the emitted waves can be varied. Required:
a. What is the longest wavelength for which there will be destructive interference at point Q?
b. What is the longest wavelength for which there will be constructive interference at point Q?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
