In the Part – I of Chapter Notes on Ray optics and Optical Instruments we have studied basic concepts such as Reflection, Refraction, Sign Convention, Lateral Shift etc. Now in this part, we will study some more important topics which are as follows:
o Total Internal Reflection

o Critical Angle

o    Application of Total Internal Reflection
      •    Mirage
      •    Optical Fibre

o Refraction by Spherical Surfaces
• Convex Spherical Refracting Surfaces

• Concave Spherical Refracting Surfaces

o Refraction by Lenses & Lens Maker’s Formula

The notes given below on the above mentioned topics and sub-topics are very important for board examination as well as competitive examination.
