A radio broadcast antenna is 36.00 km from your house. Suppose an airplane is flying 2.200kmabove the line connecting the broadcast antenna and your radio, and that waves reflected from the airplane travel 90.00 wavelengths farther than waves that travel directly from the antenna to your house.
The situation just described occurs when the plane is above a point on the ground that is two-thirds of the way from the antenna to your house. What is the wavelength of the radio waves?
