Part B簡答題部分

Solution to Problem 1：

The wavelength of the radio signals? is?λ=c/?o=25m.Clearly for?Θ=0 and?Θ=π/2 the interference is constrcutive .The amplitude of the signal picked up by the plane is twice the amplitude of the signal to the tower alone .Since intensity is proportional to the square of the amplitude,the intensity recevied is I=4I

For destrcutive interfernce we sovie

l sin(θ)=(2n+1)λ/2

where l = 100 m is the tower separation and n is aninteger . This is standard? two? source? interfernce? with the receiwer much farther way than the? spacing the sources .The angular heading? that result from

this are?θ=7.2,22.0,38.7,and61.0. A heading of 30 corresponds to constructive interference and the signal? strength from the towers would be a maximum.
