2. Lesson 5: Refraction of White Light

3. Experiences and Outcomes of Lesson Draw a diagram to show the effect of a prism on white light. State that white light is made up of all the colours shown in the visible spectrum. Identify the red and blue/ violet ends of the visible spectrum. State that TV screens produce white by mixing the 3 primary colours.
