You are examining the surface of a glass slab and notice a scratch. Changing the height of the microscope to change position of the focal point, you find that you are able to see the scratch in focus twice. Once with the microscope focused on the surface of the glass, and once with the microscope shifted 5 mm closer to the surface. What is the cause of the second image? Draw a ray diagram to help you explain. The thickness of the glass slab is 4 mm. What is the refractive index of the glass slab assuming the medium between the microscope and the slab is air (n≈1).

(15) A diver has decided to go for a night dive. Unfortunately, the crew of another small dive boat has ignored the warning floater and decided to drop an anchor in the immediate vicinity. While the diver was distracted by marine life, the diver's foot was pinned under the anchor and wedged against a rock. To escape, the diver must signal an SOS to the boat above using a powerful, but narrow beam, dive light. The diver's depth gauge reads...

EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...
Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
