All RF Cafe quizzes would make perfect fodder
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.

RF Cafe Quizzes.
Note: Some material based on books have quoted passages.
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.
Some of these books are available as prizes in the monthly
RF Cafe Giveaway.
