Demonstrate how the image formed by a plane mirror is the same size as the object, upright and laterally inverted. Use the law of reflection to explain the formation of the image. . Demonstrate and explain how a concave mirror can produce different types of image. . Demonstrate how the law of refraction [ sin(angle of incidence) / sin(angle of efraction) = constant ] applies for different refracting materials and different shaped objects. . Demonstrate internal reflection, total internal reflection and critical angle. b) Find the speed of the waves in each of the materials provided. [Speed of light in air = 3.00 x 10 ms-1] c) Choose a different type of wave and explain one practical application of reflection, one practical application of refraction and one practical application of total internal reflection.
