- Visible Light And The Solar System
- Light is refracted and reflected at surfaces and boundaries between materials.
- Telescopes
- Reflecting telescopes use a concave mirror. This gives a clearer image and allows bigger telescopes to be made.
- The Universe
- The model of the Universe changed from geocentric to heliocentric.
- Observations of the Universe in the past used light but now other types of waves are used to gain more evidence.
- Waves
- Waves transfer energy not matter. They are described in terms of wavelength, frequency and amplitude.
- Wave calculations Wavespeed= distance/time --------- Wavespeed= frequency * wavelength
- Waves transfer energy not matter. They are described in terms of wavelength, frequency and amplitude.
