In an experiment similar to Young's experiment, interference is observed using waves associated with electrons. The electrons are being produced in an electron gun. In order to increase the fringe width-

View answer and explanation

Correct option: B

Electron gun voltage be decreased.

Option B (Electron gun voltage be decreased) is correct because decreasing the voltage increases the de Broglie wavelength, thus increasing the fringe width.
