The Electromagnetic Spectrum Unit 5 Chapter 22 … Section 2

Warm-Up The E.M. Spectrum https://www.youtube.com/watch?v=bjOGNVH3D4Y Listen to the song … identify the forms of electromagnetic radiation and one example type of EM radiation one example 1. 2. 3. 4. 5. 6. 7.

The E.M. Spectrum Learning Objective: I will be able to identify how electromagnetic waves differ from each other in terms of wavelength, frequency, and energy.

Visible Light located somewhat in the middle of the EM spectrum definition: the very narrow range of wavelengths (frequencies) in the EM spectrum that humans can see located somewhat in the middle of the EM spectrum Bill Nye video: https://www.youtube.com/watch?v=gtgBHsSzCPE

The E.M. Spectrum Visible Light UV V B G O R

<tip: moving outward from Visible Light> ROYGBV The E.M. Spectrum <tip: moving outward from Visible Light> ROYGBV Infra-Red Infra = below (below the Red) The alien “Predator” used I.R. to hunt https://www.youtube.com/watch?v=nMbx3WUf89k Ultra-Violet Ultra = beyond (beyond the Violet) The “Ultraman” superhero is beyond human https://www.youtube.com/watch?v=MDAQjpBH9NM

the other one decreases The E.M. Spectrum Relationships: & As one increases, the other one decreases Example: https://www.youtube.com/watch?v=Xu6hbS2TLSw

Wavelength ( ) & Energy Bigger … lower … lower Energy The E.M. Spectrum Wavelength ( ) & Energy Bigger … lower … lower Energy Smaller … higher … higher Energy

Exit Ticket Draw your own Electromagnetic Spectrum: The E.M. Spectrum Exit Ticket On a sheet of paper, Draw your own Electromagnetic Spectrum: Include all 7 categories Show and color the Visible Spectrum After this Exit Ticket is OK’d by Mr. S, you can finish working on your Desert Life Cycle
