Lesson Activities and Sequence
The suggested sequence starts with simple manipulation of the path of light and increases in complexity through spreading light by diffraction and interference to controlling electromagnetic waves for information transfer to and from space.

  1. Simple Magnifiers
    Students use bottles, jars and water to create different magnifiers.
    Keywords: reflection, refraction, diffraction, magnification, spectrum, medium, interference

  2. Exploring Diffraction With a Spectroscope / Constructing a Spectroscope
    Students build a simple spectroscope and use it to investigate diffraction.
    Keywords: waves, crest, magnitude, diffraction, spectroscope

  3. Space Operations Learning Center
    Select the Space Communication mission training to go with this lesson. It explains how satellites transmit using the electromagnetic spectrum.
    Keywords: waves, satellites, color, spectrum, space
