If kinetic energy of an electron is reduced by (1/9) then how many times its de Broglie wavelength will increase.

Kinetic energy of a free electron is doubled. By how many times, would its de Broglie wavelength increase?

If kinetic energy of a free electron is increased by two times then by how many times will the De-Broglie wavelenght be changed?

If kinetic energy of an electron is increases by 69% then what is the percentage in its de-broglie wavelength :-

If kinetic energy of an electron is increases by 69% then what is the percentage in its de-broglie wavelength :-

If kinetic energy of an electron is increases by 69% then what is the percentage in its de-broglie wavelength :-

If kinetic energy of particle is made 16 times,percentage change in its de-Broglie wavelength will be…….

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

The kinetic energy of an electron is 4.55xx10^(-28) kJ . Calculate the de Broglie's wavelength.

The kinetic energy of an electrons is equal to the energy of photons. Show that de-Broglie wavelength of this electrons is less than the wavelength associated with a photon.
