This document discusses light and how humans see. It covers different theories of light, including that light can act as particles or waves. It describes the key components of the human eye, including the iris, cornea, pupil, lens, retina, and optic nerve. Light from the sun enters the eye and is focused on the retina to enable sight, which is one of the most important of the five senses as it allows humans to see objects and interpret colors.

2. In light and sight,you will learn about reflection and
refraction and how light enable us to see the things
in our environment.
Light also enable us to”capture moment”through
photographs.
Light from distant objects can also be captured as
described in the section on optical instruments.

3. 1. Corpuscular Theory:
light Is compose of tiny particles.
2.Wave Theory:
Light is wave
3.Electromagnetic Radiation.
4.Qantium Theory:
that are light made up of pocket of energy.
5.Photon Theory of Light:
Light is form of energy that is transferred either as a
wave or particles.

4. The three compositors how do we see?
 1.Our nature
 2.sunlight
 3.Our eyes

Different Parts Of Our Eyes

 1.Iris
 2.Cornea
 3.Pupil
 4.Lens
 5.Aqueous humuor
 6.Cillary muscle
 1, Sunlight
 7.Retina
 8.Fovea humuor
 9.Optic Nerve
 10.Vitreous Humuor

5. These enable to see objects,shape and
interpret colors.This sight is the the most
precious of the five senses.

6. The human Eye
Our eyes are probably the most
important of our five senses.
The eye is able to see in dim or
bright light but it cannot see
objects when light is absent.
This makes sight the most precious
of the five senses.

8. Visible Light Radiant Energy
Is form of radiant Energy that is
energy transferred by
electromagnetic
waves.
