Textbook Problem

(a) Calculate the velocity of an electron that has a wavelength of 1.00 μm . (b) Through what voltage must the electron be accelerated to have this velocity?

To determine

(a)

The velocity of an electron that has a wavelength of 1.00μm.

Explanation

Given:

Wavelength of electron is λelectron=1.00μm

Formula used:

Using De Broglie formula,

  velectron=hmelectronλelectron

Calculation:

Inserting data given, we obtain

  velectron=6.63×1034Js(9

To determine

(b)

Through what voltage must the electron be accelerated to have this velocity?
