Bragg Diffraction

Find Wavelength:

Move transmitter marked Red A to find peaks on the receiver. The distance you have to move the receiver between peaks will give us our wavelength.

Setup: 

See image below for setting up the lab.

Angles:

The image below shows some important tip at the angles for Bragg Diffraction.

*note* as you move the receiver you need to keep the angle between the transmitter and the line perpendicular to the cube and the angle between the receiver and the line perpendicular to the cube equivalent.

*note* “a” in the formula in the picture is distance between bearings
