Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Two radio antennas separated by d = 300 m as shown in Figure P27.3 simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x = 1 000 m from the center point between the antennas, and its radio receives the signals. (a) If the car is at the position of the second maximum after that at point O when it has traveled a distance y = 400 m northward, what is the wavelength of the signals? (b) How much farther must the car travel from this position to encounter the next minimum in reception? Note: Do not use the small-angle approximation in this problem.
The 21-cm line of atomic Hydrogen is very common throughout the Universe that some scientists suggest that if we want to send messages to aliens we should use the frequency of π times this frequency (why?). What is the frequency they suggest to use? A. 4.49 GHz B. 1.43 GHz C. 2.75 GHz D. 3.62 GHz Is the answer B? The use of frequency π times is to avoid destructive interference such that the radio message could travel through space without distortion? Thank you very much!
