# SPS9: Properties of Waves

Obtain, evaluate, and communicate information to explain the properties of waves.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SPS9.a**: Analyze and interpret data to identify the relationships among wavelength, frequency, and energy in electromagnetic waves and amplitude and energy in mechanical waves.
- **SPS9.b**: Ask questions to compare and contrast the characteristics of electromagnetic and mechanical waves.
- **SPS9.c**: Develop models based on experimental evidence that illustrate the phenomena of reflection, refraction, interference, and diffraction.
- **SPS9.d**: Analyze and interpret data to explain how different media affect the speed of sound and light waves.
- **SPS9.e**: Develop and use models to explain the changes in sound waves associated with the Doppler Effect.
