This sample set of quiz is created to train students to see relationships between different topics  in Physics. Here the areas of interest are  Old quantum theory and Development of quantum mechanics
  


 

QUIZ

  •  Two  questions are posed below. Write another question as a response to each question in such a way that to answer to the given question is hidden in your  question. 
  1. In order to explain H atom spectra Bohr postulated that all energies are not allowed. In other words the atomic energy levels are  discrete. What was an early the experimental evidence for atoms having discrete energy levels.
  2. Einstein postulated energy frequency relation $E=h\nu$ for photons to explain the photoelectric effect. Explanation of an early  experiment requires momentum of photon to be related to the wavelength by $p=h/\lambda$. Which scientist's name is associated with this experiment?

 

 Here are sample of responses expected from the students

Question 1: In order to explain H atom spectra Bohr postulated that all energies are not allowed. In other words the atomic energy levels are discrete. What was an early the experimental evidence for atoms having discrete energy levels?

Question 2: Einstein postulated energy frequency relation  $E=h\nu$ for photons to explain the photoelectric effect. Explanation of an early  experiment requires momentum of photon to be related to the wavelength  by $p=h/\lambda$. Which scientist's name is associated with this experiment?


*** Possible responses to the above question are given below. ***

Answer 1:  What is the significance of the Franck Hertz experiment on inelastic scattering of electrons from mercury vapour.

Answer 2A: What were the important conclusions of the an early electron scattering experiment that confirmed the particle nature of radiation?
Answer 2B: When was  the  X-ray scattering experiment performed which supported particle like nature of X-rays and relativistic energy momentum conservation law.

Remarks
If you enjoyed the above sample, become a volunteer and

  • prepare some sample good and some sample not so good questions.
  • create more such questions.
  • prepare guidelines to make good questions like this.
  • post your comments at the end.

This type of quizzes should be created for the whole course. It could also be useful for in mathematics courses.
