Microwaves of wavelength 4.50 cm enter a long, narrow window in a building that is otherwise essentially opaque to the incoming waves. If the window is 36.5 cm wide, what is the distance from the central maximum to the first-order minimum along a wall 6.70 m from the window?

a sintheta=1*lambda
but sinTheta=tantheta=distance/6.70

.0365*distance/6.7=lambda=.0450

solve for distance in meters.
