  • In Class:
    • Correct exams. You grade someone elses, not your own.
  • Homework:
    • Over Break:
      • Work on optics. You have 3 packets.
        • Packet One contains instructional text (Mullins Optics),
        • Packet Two contains images from your textbook.
        • Packet Three is a question packet
      • You are responsible for learning the sections on mirrors and completing packet 3.
      • Packet One has lessons labeled. For example, the right have of the front sheet has a label,
        • Lesson 4-06 Electromagnetic Spectrum, Reflection and Index of Refraction"
          • Within this section, right now, focus on Law of Reflection.
        • Lesson 4-07 Skip this section for now. We will come back to it.
        • Lesson 4-08 ALL of this is required over spring break.
        • Lesson 4-09 Skip this section for now. We will come back to it.
      • Packet Three.
        • Do ALL questions on this packet.
        • Learn how to draw two rays for ANY circumstance. Use those two rays exclusively.
        • Many places state that you should learn 3 rays. The 3rd ray is a double check of the first 2. Learn 2 rays perfectly. Use them perfectly. Then you don't need the 3rd and you save some time.
      • Sample ray diagrams online:

    • The induced B field fights to OPPOSE the CHANGE in FLUX.
    • Hold a loop of wire flat against this monitor.
    • If you move (in your mind's eye) a magnet towards the center of the loop, the B field is increasing into the loop.
    • The loop will have a current that Induces a B field to OPPOSE the change in flux.
    • Note the change in flux is increasing B into the loop. The Induced B will be a B out (towards you) of the loop.
