All RF Cafe quizzes would make perfect fodder for employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job.

Some of these books used in quizzes are available as prizes in the monthly RF Cafe Giveaway.

Note: Many answers contain passages quoted from the text.


RF Cafe Featured Book - Quantum Mechanics for NanostructuresThis quiz is based on the information presented in the book, "Quantum Mechanics for Nanostructures," by Vladimir V. Mitin, Dmitry I. Sementsov, Nizami Z. Vagidov.
Published by Cambridge University Press.
 Note: Some of these books are available as prizes in the monthly RF Cafe Giveaway.
