Two coherent sources of radio waves, A and B, are 5.00 meters apart. Each source emits waves with a wavelength of 6.00 meters. Consider points along the line connecting the two sources.

a) At what distance from source A is there constructive interference between points A and B?

b) At what distances from source A is there destructive interference between points A and B?

Two sources of periodic water waves, S1 and S2, produce circularwaves of frequency fo in a large ripple tank, as shown. The sourcesare in phase and are separated by a distance equal to thewavelength of the waves (i.e., d = λo). Point N (not shown) is apoint of complete destructive interference. Assume point N is veryfar away from the two sources. Ignore any dependence of theamplitude of a wave on the distance the wave travels from asource.

Suppose the frequency of the two sources is decreased by afactor of two, the frequency now is fo/2. After the frequency isdecreased, would the wavelength of the periodic waves increase,decrease, or remain the same?

After the frequency is decreased, would point N (previously a pointof complete destructive interference) be a point of maximumconstructive interference, complete destructive interference, orneither?

After the frequency is decreased, would the horizontal lines shownbelow be lines of maximum constructive interference, completedestructive interference, or neither?



Suppose now that the sources S1 and S2 were modified such that theyare moving completely out of phase. Would the vertical line shownbelow be a line of of maximum constructive interference,complete destructive interference, or neither?
