Question

3. Four graphs of the relative intensity vs. position for double slit interference with single slit diffraction are shown here. 0.5 0 Case 1 0.5 0 Case 2 1 Case 3 1 Case 4 0.5 0 0.5 0 a. Suppose the widths of both slits was decreased while the distance between the slits stayed the same. Which pair of graphs (one before and one after) could represent this change? Explain your reasoning. b. Suppose the distance between the slits was decreased while the widths of the slits stayed the same. Which pair of graphs (one before and one after) could represent this change? Explain your reasoning. c. Suppose the wavelength of the light source was decreased while leaving the slits unchanged. Which pair of graphs (one before and one after) could represent this change? Explain your reasoning.
