A converging lens has focal length . An object is placed from the centre of the lens, on the principal axis. Draw an accurate ray diagram to represent this.
A converging lens has a focal length . An object is placed from the centre of the lens, on the principal axis. Use your diagram. To determine the distance of the virtual image formed from the lens.
Write an equation that shows how angle of reflection and angle of incidence are related by the law of reflection. Write the equation both in words and in symbols.
Draw a diagram to show how a ray of light is refracted when it passes from one material to another. Mark the normal and the angles of incidence and refraction.
