Key Topics to Revise
1
The Human Eye - Structure and Function
- The human eye is like a camera with a natural lens system that forms images on the retina
- Light enters through the cornea (transparent front layer) where maximum refraction occurs
- The iris controls pupil size to regulate light entry into the eye
2
Defects of Vision and Their Correction
- Myopia (near-sightedness): Can see near objects clearly but not distant objects
- In myopia, distant object images form in front of the retina
- Myopia is corrected using concave (diverging) lenses
3
Refraction Through a Prism
- A prism has two triangular bases and three rectangular lateral surfaces
- The angle between two lateral faces is called the angle of the prism
- Light bends towards normal when entering denser medium (air to glass)
4
Dispersion of White Light
- White light consists of seven colors: Violet, Indigo, Blue, Green, Yellow, Orange, Red (VIBGYOR)
- Dispersion is the splitting of white light into its component colors
- Different colors have different wavelengths and bend through different angles
