However, this gives you only half the angle you need. Recall that for diffraction the 1st minima correspond with m=+/- 1, and the central maximum is everything in between. So you need to multiple the above function by 2.

MP9: Problem 22.18 (solution with explanation)
The key to this problem is the basic diffraction relationship asin (theta) = lambda, where lambda is ( the speed of light 3 * 10^ 8 m/s / the given 800 Mhz Frequency), then you multiply by 180/pi to convert to radians.
However, this gives you only half the angle you need. Recall that for diffraction the 1st minima correspond with m=+/- 1, and the central maximum is everything in between. So you need to multiple the above function by 2.

the speed of light is written wrong in the explanation.
