De-Broglie wavelength associated with an electron accelerated through a potential difference ' V ' is ' '. When the accelerating potential is increased to ' 4 ~V ', de-Broglie wavelength.

Options

  1. Areduces to half
  2. Bremains the same
  3. Creduces to (1 / 4)^ th
  4. Dincreases by 25 %

Correct answer

A. reduces to half

Step-by-step solution

De-Broglie wavelength, = 1.228 V ( ~nm ) If V is increased to 4 ~V , then will become 1 4 times or 1 2 times.
