Suppose that a slit 6.2 cm wide is placed in front of a microwave source operating at a frequency of 7.3 GHz. Calculate the angle (measured from the central maximum) where the first minimum in the diffraction pattern occurs.




I think my answer is too high ~_~

I'm not going to check the math right now but keep in mind a microwave is going to diffract a lot more than visible light since it's got a big wavelength.

Nice, just wrote the unit exam today on EMR.

I checked through your stuff and I got the same answer basically, except it would appear you aren't carrying all your digits in your calculator- very important. So I got 19.355 deg.
