I have Part C and E left ??how to do it ? Consider light from a helium-neon laser (λ=632.8 nanometers) striking a pinhole with a diameter of 0.160 mm . Part A At what angle θ1 to the normal would the first dark ring be observed? θ1 = 0.276 ∘ Correct Part B Suppose that the light from the pinhole projects onto a screen 3.00 meters away. What is the radius r1 of the first dark ring on that screen?...
