(a) How is the Young's interference pattern and intensity affected by the width of the slits, the separation of the slit, the distance of the slits from the screen, and the wavelength of the light source? Which of these parameters is it affected by most? Explain why.
(b) How is single slit diffraction pattern and intensity affected by the width of the slit, the distance of the slit from the screen, and the wavelength of the light source? Which of these parameters affects the pattern most? Explain why.
