the path of the light ray in the water(ii)Explain what happens to the wavelength of light when it passes from air into water.(2)(b)Diagram 2 shows what can happen when a light ray travelling in glass meets the boundary with air.The wavefronts are not shown in this diagram.air glas...
When light rays travel from air into glass or from air into water,it bends towards normal. This is because the speed of light rays decrease while travelling from air into glass or water. Case 2: When light rays travel from optically denser medium to rarer medium then they bend away from ...
Consider the reflection of light at normal incidence on a boundary between a glass medium of refractive index 1.4 and air of refractive index 1.0. (a) If light is traveling from air to glass, what is暂无答案更多“Consider the reflection of light at normal incidence on a boundary between a ...
When light enters a different material (e.g. when moving from air into glass), the speed of light changes. This causes the light to bend or refract. The speed of light is affected by the density of the material through which it is travelling. When light enters a more dense medium, ...

light travelling from a rarer medium to a denser medium bends towards the normal, and vice versa. glass is denser than air, and thus, when a ray of light falls on the surface of the prism, it bends towards the normal. according to the diagram, ray pe falls on the surface of the pri...
Does glass always produ 13、ce more refraction than water for rays travelling from air? Jeff has a mysterious transparent cube. He shines a ray of light onto it at an angle of 45. He measures an angle of refraction of 25. What might the cube be made from? Use the table on page 93...
