(a) and (b) are not related. (a) In a double-slit experiment, the slit separation is 30.0μm. The interference pattern is created on a screen that is 1.42 m away from the slits. If the sixth bright fringe on the screen is 10.0 cm away from the central fringe, what is the wavelength of the monochromatic light in nanometre (nm) ? (2 marks) (b) Monochromatic light of wavelength 555 nm is incident normally on a diffraction grating. If the third-order maximum of the diffraction pattern is observed at 32.0∘, what is the total number of maxima can be seen? (3 marks)
