Sketch the diffraction patterns that you would observe on a screen 1 m from an aperture illuminated by a he-ne laser (wavelength = 633 nm), for the following cases: a) a single slit, with slit width = 20 microns. b) two slits, slit width = 20 microns, slit spacing = 80 microns. draw these diffraction patterns as a function of position on the screen, with the x-axis in units of meters, and label the position of the first zero due to the "slit width" term.

Ihope you find the answer

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
