A physicist makes many measurements of the frequency of light emitted when a electron transitions from a particular excited state of an ion. For the system she is studying, the only allowed transition from the excited state is to the ground state. Her measurements have an average value of favg=2.13×1015 Hz with a standard deviation of ?f=17.4×106 Hz.
What is the minimum lifetime Δtmin of the excited state in seconds?
You are studying the absorption of electromagnetic radiation by electrons in a crystal structure. The situation is well described by an electron in a cubical box of side length L.The electron is initially in the ground state. You observe that the longest-wavelength photon that is absorbed has a wavelength in air of l = 624 nm. What is L?
Pulsed lasers are very similar to regular lasers, except they don't continuously emit laser light. Baby spice is looking at one on Ebay, and she finds a pulsed He-Ne laser that emits a cylindrical
beam of light with a diameter of 0.750 cm. Each pulse lasts for 1.30 ns, and each burst contains an amount of energy equal to 3.00 J. Baby Spice has the following questions about this laser.
(a) What is the length of each pulse of laser light?
m
(b) What is the average energy per unit volume for each pulse?
J/m³

- You are working as a demonstration assistant for a physics professor. She wants to demonstrate to her students the buildup of the interference pattern for single electrons passing through a double slit. Her source of electrons will be a certain vacuum tube, in which electrons evaporate from a hot cathode at a slow, steady rate and accelerate from rest through a potential difference of 45.0 V. After being accelerated, they travel through a fieldfree and evacuated region before they pass through the double slits and fall on a screen to produce an interference pattern. To ensure that only one electron at a time is passing through the slits, she wants the electrons to be separated in space by d 5 1.00 cm (perpendicular to the barrier containing the slits) as they approach the slit. She asks you to determine the maximum value for the beam current that will assure that only one electron at a time passes through the slits.arrow_forwardA thin solid barrier in the xy-plane has a 12.6µm diameter circular hole.
