If the kinetic energy of a moving particle is E , then the de-Broglie wavelength is

If the kinetic energy of a moving particle of mass m is E, then the de Broglie wavelength lambda is

If the kinetic energy of a particle is doubled, de Broglie wavelength becomes:

If the kinetic energy of a particle is doubled, De-Broglie wavelength becomes :

If kinetic energy of emitted electron is made double then its de-Broglie wavelength will become……times initial de-Broglie wavelength.
