Paper or card. Angle a directed ray of light to the underneath of the surface and total internal reflection can be seen (it is easier to see with the lights off). For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction.How much does light bend?The amount of bending depends on two things: 1. As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). Few more from Stem Activities for Kids. But how do you turn it green? Using only a few materials, you can demonstrate how light can be bent. As the light travels through a substance, it becomes concentrated into a focal point, … Which of the angles is larger? When light slows down or is refracted through another material, it may appear to bend rather than travel in a straight line. It's super simple and you can set it up within minutes.
