A bowling ball has well- defined position and speed, whereas an electron does not. Why?
Answer to relevant QuestionsA laser requires a metastable state that is a relatively long- lived excited atomic state. What is the uncertainly in the energy of the metastable state compared to non-metastable excited states? A scientist wants to use an electron microscope to observe details on the order of 0.25 nm. Through what potential difference must the electrons be accelerated from rest so that they have a de Broglie wavelength of this ...(a) How many possible sets of quantum numbers are there for the n = 1 and n = 2 shells? (b) Write the explicit values of all the quantum numbers (n, ℓ, mℓ, ms) for these levels. Write the ground state electron configurations for each of the following atoms: (a) Boron (b), (b) Calcium (Ca), (c) Zinc (Zn), and (d) tin (Sn). The energy of a 2.00-keV electron is known to within ± 3.00%. How accurately can its position be measured?
