Consider the sequence of Stern-Gerlach devices in the figure. Suppose that an electron entering the last device emerges from the + or - channel with probabilities 4/5 and 1/5, respectively. What are the two distinct angles theta between -180o and +180o that are consistent with these results? (Hint: the answer is +/- 127o)

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
