The document discusses early models of light including the particle and wave models. It focuses on Newton's particle model and how he showed light travels in a straight line through reflection and refraction. It also discusses how the wave model can explain phenomena like diffraction and dispersion that the particle model could not. Finally, it mentions Young's experiment determining the wavelength of light and Einstein's explanation of the photoelectric effect supporting light having both wave and particle properties.

1. Nature of Light Part 2 Review:
Several early models used to explain the nature
of light were:
