If the potential difference used to accelerate electrons is doubled, by what factor does the de-Broglie wavelength associated with electrons change?

Options

  1. AWavelength in increased to 1 2 times.
  2. BWavelength in increased to 1 2 times.
  3. CWavelength in decreased to 1 2 times.
  4. DWavelength in decreased to 1 2 times.

Correct answer

C. Wavelength in decreased to 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.
