If the potential difference used to accelerate electrons is doubled. By what factor does the deBroglie wavelength ( ) associated with the electrons change?

Options

  1. Ais increased to 2 times.
  2. Bis increased to 1 2 times.
  3. Cis decreased by 1 2 times.
  4. Dis decreased by 2 times.

Correct answer

C. is decreased by 1 2 times.

Step-by-step solution

From = h 2 mqV , 1 V If potential difference is doubled, 1 2 ~V is decreased by 1 2 times.
