Even with this erroneous speculation, the Greeks were being capable of successfully study the phenomena of reflection and refraction and derive the regulations governing them. In reflection, they realized the angles of incidence and reflection were about equal; in refraction, they saw that a beam of light would bend mainly because it entered a denser medium (for instance drinking water or glass ) and bend back exactly the same amount since it exited.
Although this may seem paradoxical, it stays an acceptable model for conveying the phenomena linked to light and is also the dominant theory of our time.

What does create a big difference is the color in the light. Red light, for instance, creates a lot more of a present than blue light.
The cones reply to here bright light; other buildings known as rods reply to dim light, as well as the pupil regulates the amount of light that enters the attention.
