10) A small insect is placed between a 6.0 cm long air wedge formed by two pieces of glass. 770 nm wavelength light produces an interference pattern of 86 bright fringes with a dark fringe at each end.Calculate the thickness of the insect in m.

9) The angle to a bright fringe in a single-slit interference experiment is 3.5. What order must this maximum be, if the wavelength of light is 580 nm and the width of the slit is 52 m?

8) Light of wavelength 570 nm passes through a 32 m single slit and produces a 6.7 cm wide central maximum. How far away is the screen that displays the diffraction pattern from the slit?
