The electron beam in a colour TV is accelerated through 32 kV and then strikes the screen. What is the wavelength of the most energetic X-ray photon?

In an old-fashioned television set, electrons are accelerated through a potential difference of 25.0 kV. What is the de Broglie wavelength of such electrons? (Relativity is not needed.)

An electron experiment was performed with a beam of electron accelerated by a potential difference of 10.0 k eV .What is the wavelength of the electron beam

An electron experiment was performed with a beam of electron accelerated by a potentail difference of 10.0 k eV .What is the wavelength of the electron beam

The kinetic energy (K.E.) of a beam of electrons, accelerated through a potential V, equalws the energy of a photon of wavelength of 5460 nm. Find the de-Broglie wavelength associated with this beam of electrons.
