Today's Goals

  • Review Unit 4 for Extra Credit

  • Go over major assessments (alternative portfolios & tests)

  • Answer any questions you may have

3

Unit 4 - Waves & Electromagnetic Radiation

  • Investigate and interpret the relationship between properties of waves and various wave behaviors and characteristics

  • Summarize various ways modern technology uses waves to enhance communication

4

Properties of Waves

  • A wave is a disturbance that transfers energy from one location to another

  • Some waves require a medium to travel through (mechanical waves)

  • Other waves do not require a medium to travel through (electromagnetic waves)
