Refraction Of Light Diagram. Demo showing students how to draw ray diagrams for the refraction of light through glass and perspex blocks. Refraction is the change in direction of a wave at such a boundary.
We shall try to understand in this chapter the r eflection of light by spherical mirrors and refraction of light and their application in real life situations. Draw a line at 20o to the normal. Suitable for ks3 and gcse physics.
Once the light ray refracts across the boundary and enters the lens it travels in a straight line until it reaches the back face of the lens.
Index of refraction. Violet light slows down even more than red light so it is refracted at a slightly greater angle. These basic concepts will help us in the study of some of the optical phenomena in natur e. Demo showing students how to draw ray diagrams for the refraction of light through glass and perspex blocks.
