EM Spectrum Thursday, April 14, 2016

Unit 11: EM Spectrum/Optics Thursday, 4/14  Draw the mind map below on your notebook. Think back to the article you read after the test last week. Predict what will be drawn under the EM wave section. Upcoming dates:  Monday, 4/18 – EM Spectrum/Optics quiz  Tuesday, 4/26 - EM Spectrum/Optics quiz  Thursday, 4/28 – EM Spectrum/Optics test all missing EM Spectrum/Optics work is due (missing work is a zero after you test)  Friday, 5/6 – Atomic Physics test all missing Atomic physics work is due (missing work is a zero after you test)  Monday, 5/16 – Rube Goldberg Project due (test grade)  Friday, 5/20 – Bottle Rocket launch day (test grade)  Thursday, 5/26 – Exam review due (it is 30% of your exam grade)

Guiding Questions 1. If electromagnetic waves don’t require a medium what is vibrating (causes the disturbance)? (resource 1) 1. What do wavelength and frequency tell us about a wave? (resource 1) 2. There are seven regions in the EM spectrum. What is used to define the regions? What are the names of the regions? (resource 1 and 2) 3. Summarize key points about each region of the EM spectrum (resource 2). 1. How can you use a diagram to describe the various energy levels of the EM spectrum? (include a diagram of the EM spectrum in your response). (resource 2) 1. What velocity do EM waves travel? (resource 3)

Guiding Questions (Cont.) How can you use a diagram to describe the various energy levels of a EM wave? (include a diagram of the EM spectrum in your response). (resource 2)

Visible Light Spectrum

Practice Problems  When you are finished with your practice problems do the following:  Show me your completed work.  Check your answers.

EM Spectrum Assignment Draw the EM Spectrum and include the following: 1. Draw the wavelength and frequencies of each EM wave to scale. 1. Label the 7 different EM waves. 2. List two facts you have learned about radio waves, microwaves, infrared waves, ultraviolet waves, x-rays, and gamma rays. 3. Diagram the visible light spectrum and describe how each of the waves in the spectrum are different.

Cool Down  What is the smallest part of the EM Spectrum?
