A beam of electrons is accelerated from rest through a potential difference of 0.120 kV and then passes through a thin slit. The diffracted beam shows its first diffraction minima at ±13.0∘ from the original direction of the beam when viewed far from the slit. Do we need to use relativity formulas? explain pleaseHow wide is the slit?

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?
