WebBackground: Studies of molecular changes in hair as possible biomarkers for specific cancers revealed an additional molecular change in the diffraction patterns of some persons aged over 75. This change was found to correlate with the presence of Alzheimer's disease (AD). To confirm this correlation and its relation to the presence of a human APP … WebJul 16, 2015 · 3. Some of the light is blocked by the wire. But the light passing immediately off the upper and lower edges of the wire's silhouette act as two point sources, which interfere with each other when they reach the screen behind the wire. Babinet's principle says that the diffraction pattern from the edges of an opaque body is the same as that ...
