A photon of blue light and a photon of red light are traveling in vacuum. The photon of blue light
 
  A) has a smaller wavelength than a photon of red light and travels with the same speed.
  B) has a smaller wavelength than a photon of red light and travels with a greater speed.
  C) has a longer wavelength than a photon of red light and travels with the same speed.
  D) has a longer wavelength than a photon of red light and travels with a greater speed.

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?

To prove that stomach ulcers were caused by bacteria and not by stress, a researcher consumed an entire laboratory beaker full of bacterial culture. After this, he did indeed develop stomach ulcers, and won the Nobel Prize for his discovery.

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
