Speed of Light
A. H. L. Fizeau
Realized the first realiable measurement of the speed of light. The velocity he calculated was 3.13x10^8 m/s.
Albert A. Michelson
Used Foucault's method . Obtained very accurate measurements to determine that the speed of light in air is 2.97x10^8 m/s.
Olaus Roemer
Was the first to estimate the speed of light. He calculated that the speed of light was: v= s/t =3x10^11m / 1300s = 2.31x10^8 m/s

Lenses
They are transparent objects and are limited by two surfaces: one spherical and one flat, or by two spherical.They refract light as they alter the shape of a front of waves.
Converging lens
Converges and refracts a parallel light at a focal point(F) beyond the lens. Thicker in the center and taper at the ends. Used in cameras, microscopes, etc.
Diverging lens
Refracts and diverges parallel light from a F located in front of the lens. Thinner at the center than at the ends. For people who suffer from myopia.
Reflection of Light
Phenomenon that describes how light returns to its original medium as a result of an impact on a surface.
Whe the surface the lights reflects from is smooth, the rays are reflected in a single direction and this surface is called a mirror.
The ray that reaches the mirror is called incident and the repulsed ray, reflected.
When an incident ray touches an irregular surface, the ray is not well defined and the light is scatterd in all directions.
This phenomenon is called diffuse reflection or diffusion of light
