Please answer a and b Question b has the same option as (a) Same pictures Thank you

(4%) Problem 20: In a single-slit diffraction experiment, a coherent light source illuminates a slit in a barrier, and the resulting pattern is projected on a screen that is separated from the barrier by a distance which is very large as compared to the slit width and the wavelength of the light source. A student makes sketches of the resulting patterns. While the center of each bright or dark band is accurately represented, the shading is qualitative, and the choice of color may not reflect the wavelength of the light source.

D A 50% Part (a) The student performed multiple iterations of the same experiment. In each iteration, the only parameter that was changed was the width of the slit. Which of these patterns corresponds to the most narrow slit width?

In each iteration, the only parameter that was changed was the wavelength of the coherent light source. Which of these patterns corresponds to the light with the shortest wavelength? The student made all of the sketches using the same color even though the light sources had a variety of colors
