Question

Good morning, today I present some exercises, thank you for helping me with the solution to understand the concept after each exercise.

Exercises

Light absorbed as photons: The photoelectric effect":

The braking potential for electrons expelled from a surface of a given material is 2.42 volts when an 1849 Å ultraviolet light strikes the plate. What will the braking potential be if a light with a wavelength of 265.0 nm strikes the same plate?


Theme (2.2) "Light emitted as photons: Production of x-rays":

Protons are accelerated from rest by a potential difference of 2.1 kV and collide with a metallic target. If a proton produces a photon on impact, what is the minimum wavelength of the resulting x-rays?


3: Theme (2.3) "Scattered light in the form of photons: Compton scattering and pair production":

An x-ray with an initial wavelength of 0.07 nm experiences Compton scattering. What is the longest wavelength found in scattered x-rays? At what scattering angle is this wavelength observed?
