3. A single slit is used to create an interference pattern on a screen using light. Consider the statements that follow with respect to the pattern generated: I. A longer wavelength of light generates a wider central maximum. II. When using white light, the outer fringes are coloured. III. A narrower slit generates a wider central maximum. Which of the above statements is/are incorrect? a. b. c. I only I and II only I and III only d. e. I, II, and III none
