Energy transfer through different mediums can be explained using wave and particle models (ACSSU182)
Energy transfer through different mediums can be explained using wave and particle models (ACSSU182)
- explore how and why the movement of energy varies according to the medium through which it is transferred
- discuss the wave and particle models and how they are useful for understanding aspects of phenomena
- explore the properties of waves, and situations where energy is transferred in the form of waves, such as sound and light
- Consider how technologies have been developed using optical fibers and polarizing filters
- Consider how communication methods are influenced by new technologies that rely on electromagnetic radiation - light

The Properties of Light and SoundBoth light and sound are forms of energy and both can be transformed into other sorts of energy.
Photosynthesis turns light into chemical energy Solar cells turn light into electrical energy Radios turn kinetic energy into sound energy Light travels in straight lines called rays. Measuring Angles |
