Problem 20: Consider 642 nm light falling on a single slit of width 19.5 μm. Randomized Variablesλ = 642 nm w = 19.5 μm Part (a) Find the angle, in degrees, of the third diffraction minimum for the light. Numeric : A numeric value is expected and not an expression. θ3 = __________________________________________ Part (b) What slit width (in micrometers) would place this minimum at 85.0°? Numeric : A numeric value is expected and not an expression. w' = __________________________________________
