Photoelectricity and electron microscopy

(D) The particle nature of light is demonstrated by the photoelectric effect,where light behaves as a stream of photons. The wave nature of electrons is demonstrated by electron microscopy,where an electron beam behaves as a wave with a specific wavelength (de Broglie wavelength) to achieve high resolution. Thus,both natures are exhibited by these phenomena.

View Solution

The de-Broglie wavelength of an electron is the same as that of a photon. If the velocity of the electron is $25 \%$ of the velocity of light,then the ratio of the $K.E.$ of the electron to the $K.E.$ of the photon will be:

Two electrons are moving with the same speed $v$. One electron enters a region of a uniform electric field,while the other enters a region of a uniform magnetic field. If the de-Broglie wavelengths of the two electrons after some time are ${\lambda _1}$ and ${\lambda _2}$ respectively,then:
