- Light Theories
- Newton's Particle Theory of Light
- Colours- mass of the particle varies with colour
- Reflection- angle of incidence is equal to the angle of reflection
- The speed of light is different depending on the materials
- Refraction- no force on the particle in a medium, force of attraction in dense mediums, the wave speeds up, velocity is deflected
- Huygen's Wave Theory of Light
- Light is made up of waves propagated through space
- Refraction-light is a transverse wave, waves superimpose:reinforce or cancel each other out
- Thomas Young's Double Slit experiment
- Colours-different wavelengths of light give different colours (red is the longest)
- Wave enters a slower medium from a fast one and slows down
- Newton's Particle Theory of Light
