Question 11 ( a. In an investigation into single-slit diffraction, a laser is used to produce an interference pattern on a screen. Use the following measurements to determine the wavelength of light in three different ways. • The angle to the third dark fringe is 2.6°. • The distance from the slits to the screen is 3.00 m. • The distance from the centre of the central maximum to the second dark fringe is 9.0740 cm. • The distance from the first maximum to the third maximum is 9.072 cm. • The width of the slit is 0.0500 mm. b. What are two possible changes that would each result in an increase in the number of nodal lines visible on the screen? c. What changes would occur if the light were shone through (i) a pair of slits orlii) a diffraction grating? What would cause these changes
