You need to use your cell phone, which broadcasts an 970 MHz signal, but you're behind two massive, radio-wave-absorbing buildings that have only a 17 m space between them. What is the angular width of the electromagnetic wave after it emerges from between the buildings?

Answer 1

Answer #1

thetamin = arcsine (wavelength / width of slit) = arcsine (speed of light / (frequency * width of slit) )

=(3*10^8/(970*10^6*17))

= 0.0182 That is the angle between the central max and the first minimum. So I suppose if you want the total width of that first hump, double it I.e= 0.0364
