Solve the all parts of following problem:
Problem: In order to have a clear diffraction pattern the slit must be around the same order of magnitude as, but not smaller than the wavelength of the light.
Part A: What is the ratio of single slit width to wavelength for your experiment?
Part B: How would the pattern on the wall change if you could gradually widen the slit?
I want help to find the ratio of single slit width to wavelength for your experiment.
