Title: Define electromagnetic spectrum.
Course: Geospatial Technology II (21058-II) > Section: Working with Raster Data and RS

Definition should include

- frequency, wavelength, hertz, Planck's constant, and speed of light
- the relationship between the electromagnetic spectrum and the methods for collecting RS data
- types of radiation, such as
  - visible light
  - ultraviolet light
  - infrared
  - radio
  - gamma
  - X-ray
  - microwaves.

Process/Skill Questions:

- How do frequency and wavelength relate to RS?
- What devices use part of the electromagnetic spectrum in RS?
- What are the major sections of the electromagnetic spectrum?
- What are the differences between active and passive sensors?
