According to the Heisenberg uncertainty principle, how accurately can the position of the Ag atom be measured along the direction of motion? 7. Expectation value. A series of measurements of an observable Q on identically prepared quantum systems gave the following integer-valued outcomes: = -5, -3, -2, -2, 0, 1, 4, 4, 4, 9, 12. (a) Compute the expectation value (= mean), 〈 〉? (b) Compute the uncertainty (= standard deviation = root-mean-square deviation), . (c) What is the median? (d) What is the most likely value (= mode). ∑ (a) The mean is 〈 〉 .00. (b) The expectation value of th...
