OP3.6 Young's Experiment Using Microwaves
The apparatus consists of two microwave generators and one meter. The generators are placed a small distance away from each other, facing the same direction. The meter is carried by the instructor in front of the genera-tors. The meter, big enough so that the class sees the needle move, shows peaks and zeros of the interfering waves. An AC hum can be used as an auditory indicater of intensity. The wavelength of the microwaves is 12cm. Instead of using the two sources, replace the clip in the generator by a paper clip that would act like a dipole, which would demonstrate the dipole pattern. This pattern will follow the sine squared law: zero directly above the dipole and maximum perpendicular to it.
