An electron is trapped in an infinite square well (a box) of width Find the wavelength of photons emitted when the electron drops from the n = 5 state to the n = 1 state in this system.
 
  (c = 3.00  108 m/s, h = 6.626  10-34 J  s, mel = 9.11  10-31 kg)
  A) 6.49 m
  B) 5.45 m
  C) 5.91 m
  D) 7.07 m

Question 2

An electron in an infinite potential well (a box) makes a transition from the n = 3 level to the ground state and in so doing emits a photon of wavelength 20.9 nm. (c = 3.00  108 m/s, h = 6.626  10-34J  s, mel = 9.11  10-31 kg)
 
  (a) What is the width of this well?
  (b) What wavelength photon would be required to excite the electron from its original level to the next higher one?
  What will be an ideal response?

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.

Vaccines cause herd immunity. If the majority of people in a community have been vaccinated against a disease, an unvaccinated person is less likely to get the disease since others are less likely to become sick from it and spread the disease.
