Reminders

  • Temporary zeroes (*0s) will go in on Friday morning for ALL unfinished lessons

  • I sent out a webmail yesterday that contains recording that go over your portfolios question-by-question

  • There is also a recording that goes over your Unit 4 test, question-by-question

  • Remember to ask for resets, if needed!

  • 12 school days left, including today!!!

Electromagnetic Spectrum

  • Electromagnetic radiation is energy that travels in waves across space as well as through matter

  • Characterized by certain wavelengths & wave frequencies

  • Wavelength = distance between 2 corresponding points on adjacent waves

  • Wave frequency = # of waves that pass a fixed point in a given amount of time

  • Shorter wavelength = higher frequency
