Study Notes

Double-slit experiment: A viewing screen is separated from the double-slit source by a certain distance. The distance between the two slits is another distance. The second-order bright fringe (m = 2) is a certain distance from the center line.
Bright fringe width: The bright fringe width is defined as the distance between two adjacent destructive minima. The formula for calculating the bright fringe width is y = m d L1 / (m + 1) - m = d.
Taylor experiment: In 1909, G.I. Taylor performed an experiment with a very dim light source and observed the production of an interference pattern even with only one photon passing through the double slit at a time.
Quantum theory: The basic idea of quantum theory is the impossibility of imagining an isolated quantity of energy without associating with it a certain frequency.
Heisenberg’s Uncertainty Principle: It helps examine the dual nature of light, electrons, and other particles. A particle’s position and momentum are uncertain, and the more precisely one of them is known, the less precisely the other can be known.
Quantum communications: Alice and Bob can use quantum keys to ensure their communication remains private. However, Eve's measurements of a quantum signal can cause perturbations that can be detected.
Double-slit experiment with different conditions: Closing one of the slits results in no interference pattern. Monitoring which slit a single photon entered also eliminates the interference pattern. Using electrons instead of photons also destroys the interference pattern due to the larger photon momentum.
Double-slit experiment problem set: Q1 asks for the angle of the first-order maximum for 450-nm wavelength blue light, Q2 asks for the angle of the third-order maximum for 580-nm wavelength yellow light, Q3 asks for the separation between two slits for the first maximum of 610-nm orange light at an angle of 30.0°, Q4 asks for the distance between two slits for the first minimum of 410-nm violet light at an angle of 45.0°, Q5 asks for the wavelength of light that has its third minimum at an angle of 30.0° when falling on double slits separated by 3.00 μm, and Q6 asks for the wavelength of light falling on double slits separated by 2.00 μm if the third-order maximum is at an angle of 60.0°, Q7 asks for the angle of the fourth-order maximum in the given situation.
