JA beam of electrons is accelerated from rest through a potential difference of 0.100 kV and then passes through a thin slit. When viewed far from the slit, the diffracted beam shows its first minimum at ± 14.6° from the original direction of the beam. A) What is the velocity of the electrons? B) What is the de Broglie wavelength of the electrons?The Compton Effect is a fundamental phenomenon in physics that describes the change in wavelength of electromagnetic radiation (such as light) when it interacts with charged particles, such as electrons. When photons (particles of light) collide with electrons, some of their energy is transferred to the electrons, resulting in a change in the direction and wavelength of the scattered photons.
