Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927)
An experiment which conclusively confirmed the wave nature of electrons; diffraction patterns were observed through an electron beam penetrating in a nickel target.
A rectangular rosette is mounted on a test structure as shown, loads are applied, and the following strains are measured by strain gage elements 1, 2, and 3: ε 1 = 1500 μm/ m ε
Q. Compute the resistance of the filament of a 100W, 220 V electric bulbs. Power P = V 2 /R Resistance R = V 2 /P = (220 X 220)/ 100 = 484 ohm.
