RAY OPTICS -I Refraction of Light: Refraction is the phenomenon of change in the path of light as it travels from one medium to another (when the ray of light is incident obliquely). It can also be de When light travels from one material to another it usually changes direction. The bending of light that occurs at the borderline of two materials is called . refraction.

From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . What has happened in each example and why?. I think this is called.... It happens when.... It happens because.... The air is.... The water is.... The light usually. travels...but when it hits water.... What is Refraction?. In a vacuum (air) light travels in straight lines.. But what happens when light travels from one material into another?. Like for example, from air to water?. What Happens When Light hits a Medium. Presented by: Vandana Bathla & Eric Williams. Light Refraction. Have you ever wondered why it appears we see puddles of water on a highway on a hot summer day?. What you are seeing is not really water, but a mirage.. Refraction occurs at a boundary. The speed of light must change at the boundary. The angle of the light ray is measured from the normal, as was the case with reflection. If the speed slows across the boundary, the refracted angle will be smaller – the light ray will bend toward the normal.. Define refractive index.. Demonstrate refraction..

Refraction of light occurs when a light wave moves from a vacuum (or a medium) into another medium (or a vacuum). When a wave changes media, its ____________ changes..
