The probability of an electron penetrating barrier of 10 eV is equal to 0.8 %.  If the width of the potential barrier is 0.6
nm, find the energy of the electron.

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.
