Presentation Transcript

  1. Analysis for Optics Lab • Choose 6 hypothesis/data sections and analyze the hypothesis and the data • Briefly summarize the experimental setup • Summarize the data and explain WHY the observed phenomenon occurred • Discuss whether the results proved or disproved your hypothesis

  2. Differences between mirrors and lenses • Light reflects from a mirror • Light goes through and is refracted by a lens

  3. Law of reflection

  4. Concave Mirror Concave mirror converges light to a focal point

  5. Convex mirror Convex mirror diverges light

  6. Convex Lens Thicker in the middle than at the edges Thick lenses with highly curved surfaces bend light more than thin ones with less curved surfaces • Light rays approaching the lens parallel to the optical axis are refracted toward the center of the lens • Amount of refraction depends on the change in the speed of light as it passes through a material

  7. Concave Lens • Thinner in the middle and thicker in the edges • Light passing through a concave lens bends toward the edges • The rays diverge

  8. When a light beam goes from air to glass or plastic at an angle, it is bent toward the normal • The beam in the first medium is called the incident ray, and the beam in the second medium is called the refracted ray. • How much the light bends is based on the angle of incidence and the properties of the medium (glass has a higher index of refraction than water)
