Solution

In the Davisson and Germer experiment, the velocity of electrons emitted from the electron gun can be increased by increasing the potential difference between the anode and filament.

The quantity\(\frac{e^{2}}{2h\varepsilon _{0}c}\)

In case of electrons and photons having the same wavelength. What is same for them?

White X-rays are called white due to the fact that

they are electromagnetic radiations having nature same as that of white light.
they are produced most abundantly in X ray tubes.
they have a continuous wavelength range.
they can be converted to visible light using coated screens and photographic plates are affected by them just like light.

The ratio of de-Broglie wavelengths of proton and α-particle having same kinetic energy is
