Presentation Transcript

  1. Light Learning Targets 

  2. Light • I can calculate the illumination or luminous flux given a radius or distance. • I know what the terms illumination and luminous flux mean. • I know the possible labels for illumination and luminous flux.

  3. Light • I know about light through different mediums. • I know the speed of light. • I can identify examples of transparent, translucent and opaque. • I can recognize the parts of the electromagnetic spectrum

  4. Colors and pigment • I know the primary colors of light and pigment. • I know the secondary colors of light and pigment. • I know the complementary colors of light and pigment.

  5. Colors and pigment • I can calculate the illumination or luminous flux given a radius or distance. • I know what term illumination and luminous flux mean. • I know the possible labels for illumination and luminous flux.

  6. Answers to page 452 • 42) Black does not reflect any light. • 43) Yellow-green (550 nm) is easiest to spot. • 44) Yellow light will show yellow paint better. • 45) Diminish by an inverse squared factor. • 46) Will not change, the lamp stays the same. • 49) Yellow, add colors of light. • 50) Black, subtract pigment colors. • 51) Mix just the cyan and magenta.

  7. Mirrors • I can draw reflected ray diagrams using angle of incidence = angle of reflection. • I know the terms: principal axis, concave, convex, focal length, focal pt., geometric center, inverted, converge, diverge, real image, virtual image, spherical aberration and chromatic aberration.

  8. I know how rays of light reflect (ie, light parallel to the principle axis and light through the focal point) • I can create a ray diagram. • Given an object and a mirror I can fully describe the image • Fully describe—real/virtual, relative size, relative location, upright/inverted

  9. I can calculate the image distance given focal length and distance from mirror. • I can calculate heights and distances given magnifications • I know mathematically how focal length and center of curvature are related.

  10. Exit papers • 1) Name one physics topic you learned today. • 2) Name another you learned or improved on today. • 3) Tell me the topics, covered today, that you may need to see more of.
