1. Read your entire light and wavesscale in your comp book and your

Electromagnetic waves chart from the exam day project

2. Think about what you already learned about waves – be prepared to discuss.

3. Title the next space in your comp book “Waves Overview”

Copy this Overview• A wave is a disturbance that transfers energy• Because of the L of CE, the energy travels through the

wave and/or gets transformed into thermal energy due to friction (why sound is distorted)

• There are different types and categories of waves• Different mediums affect the wave speed • With no medium (through space) EM waves travel at the

speed of light/light speed (300,000 km per second or 670,000,000 mph)

• EM waves are how the suns energy gets to Earth • Light year – how far light travels in a year (it is a distance

measurement…about 9.5 trillion kilometers or 5.88 trillion miles)

TO DO1. Mechanical Waves vs Electromagnetic Waves

Foldable (instructions at your table)

2. Waves Concept Map– Fill in the missing items (and check your answers)– Glue into your comp book

3. If time, read and complete Ch 9 Lesson 1 in textbook.
