When radio waves try to pass through a city, they encounter thinvertical slits: the separations between the buildings. this causesthe radio waves to diffract. in this problem, you will see howdifferent wavelengths refract as they pass through a city andrelate this to reception for radios and cell phones. you will usethe angle from the center of the central intensity maximum to thefirst intensity minimum as a measure of the width of the centralmaximum (where nearly all of the diffracted energy isfound). consider radio waves of wavelength λ entering a city where the buildings have an average separation of a. part a find the angle θ to the first minimum from the center of the central maximum. express your answer in terms of λ and a

May someone explain how to do this question?
