Question

(Stern-Gerlach experiment) Discuss Stern-Gerlach experiment and show that the electron and proton have intrinsic angular momenta called spins confined to two values. What is the root mean square speed of silver atoms passing through the slits of the Stern-Gerlach apparatus after evaporating in the oven at 2227° C?

Answer 1

STERH-GERLACH EXPERIMENT According to stern gereach experiment the spatial Orientation of angular momentum is quantized. ↑ SPIN UP ATOMS OD - -SPPM Down OVEN ATOMIS In this experiment Ag atom passes through spatically varying magnetic field, which deflected them before they stuck with screen. Note that particle having non zero magnetic field deflected because of magnetic field gradient. On the screen there are discrete pornt of accomodation, rather than a continuous distribution owing to these quantized spin. (Intrinsic angular momenta) + 1/2 and - Spin Lorent force acting on electron and path will be circle. Electane field cancelled this force. Electrons chaving (2) spin.
