Student 1 and Student 2 conducted experiments using coherent sources of light, with Student 1 using a single slit and Student 2 using a double slit. The figure shows three patterns A, B and C.
Give two reasons that assisted you in recognizing the patterns.

Official answer key
Student 1- Utilisation of a single slit results in a diffraction pattern, characterized by a wider central maximum and diminishing fringe widths as they extend. Conversely, Student 2- Utilisation of double slits yields an interference pattern, as evidenced by uniform fringe widths across the pattern. Pattern C conforms to a diffraction pattern due to its wider central maximum and progressively decreasing fringe widths, while pattern B exhibits equal fringe widths indicative of an interference pattern.
