(b) The following results are obtained in a double-slit experiment using light from a helium-neon gas laser: Width of 15 fringes = 3.0 cm Separation of slits = 1.5 mm Slit-to-screen distance = 2.5 m Find the wavelength of light. (2 marks) Question 4 (a) (b) A Young's interference experiment is performed with monochromatic light. The separation between the slits is 1.50 mm, and the interference pattern on a screen 4.0 m away shows the first side maximum 2.8 mm from the center of the pattern. Find the wavelength. (1 mark) Young's double-slit experiment is performed with 650 nm light and a distance of 1.5 m between the slits and the screen. The tenth interference minimum is observed 8.5 mm from the central maximum. Find the spacing of the slits. (2 marks) (c) Explain how the double slit splits the wavefront of light rays with a diagram.
