EM Waves 04

OPENING QUESTION: What is the wavelength of light with a frequency of 1295 megacycles?

How much energy does ONE photon of that light carry?

What uses has the FCC set aside for that type of light?

═══════════════════════════

LEARNING TARGET: I will investigate how astronomers study each type of light in the EM Spectrum during today's class

WORDS O' THE DAY:

  • hertz (Hz): a measure of wave frequency in waves/second
  • electromagnetic waves (light waves from radio - gamma)
  • quantum jump
  • energy levels
  • excited (electron) = ("electrons 'jolted' into a higher energy level")
  • rest state (electron) = ("electrons existing on the lowest energy level")

FORMULAE OBJECTUS:

h = Plank's Constant = (6.63 x 10-34 m2kg/s)

c=λυ: The speed of light (c) = wavelength (λ "lamda") x frequency "nu")

E = hυ (The energy in a photon of light is given by Plank's Constant times the frequency of that light

CALENDAR:

Test returns today

Test on light waves on Thursday

Begin TFAD work on Friday

WORK O' THE DAY:

═══════════════════════════

Let us return to our project to examine the various types of RMIVUXG light:

By the end of class today you should have:

    • A list of all the types of light in some sort of order

    • A well-crafted, thoughtful explanation of how that type of light is created by humans here on Earth

    • Several well-crafted, thoughtful descriptions of how we as humans use or experience that type of light here on Earth

    • An example of the specialized equipment ASTRONOMERS use to observe phonomena in that type of light in the Universe.

    • A picture of an astronomical object photographed in that type of light
