Upon completion of this lesson, student must be able to:

  • Distinguish between transparent, translucent and opaque object with their examples.
  • Draw ray diagrams for image formed by spherical mirrors.
  • Distinguish between concave and convex mirror with their uses.
  • State laws of reflection and refraction.
  • Define critical angle and total internal reflection.



This note presents us the information about spherical mirrors, terms used in a spherical mirror, the position and the nature of the image formed by a concave mirror and differences between concave and convex mirror. Refraction with its laws is briefly described. Learn More

Refraction of The Light

The bending of light as it passes from one transparent medium to another medium is called refraction of light. Refraction of the light note provides an information about Laws of refraction, definition of refraction with the example. Learn More
