Question by Giancoli, Douglas C., Physics: Principles with Applications, 7th Ed., ©2014, Reprinted by permission of Pearson Education Inc., New York.
Problem 45
Q

Calculate the de Broglie wavelength of an electron if it is accelerated from rest by 35,000 V as in Fig. 27–2. Is it relativistic? How does its wavelength compare to the size of the “neck” of the tube, typically 5 cm? Do we have to worry about diffraction problems blurring the picture on the CRT screen?

Cathode rays deflected by electric and magnetic fields. (See also Section 17–11 on the CRT.)
