OUTCOME
By the end of this lesson you will be able to use the ray model of light to show the path light travels when reflecting and refracting. You will be able t use Snell's law to predict the angle of incidence of refraction through different mediums
Images can be described as real or virtual. All objects follow the law of reflection, but an image is formed when the light is reflected uniformly. Refraction if the bending of light when it passes from one medium to another and can be described mathematically with Snell's Law
