Refraction using a semicircular glass block
WebRefraction is the change of direction of wave that occurs when its speed changes. Refraction is a phenomenon that is exhibited by wave when it travels from one medium to another, for example, when light travels from air to glass or vice versa. Refraction can be also be seen when water waves move from deeper into shallower water. A. Refraction Web1) REFRACTIVE INDEX (n) OF A MATERIAL When a ray of light is shone from air onto the flat face of a semi-circular block of transparent material which is denser than air, at any angle other than 90o, the ray changes direction on entering the material (due to a change in velocity) - The ray is refracted: The constant is known as the refractive index of the material.

In this required practical activity, it is important to: make and record the angles of incidence and the … Webrefractive index to one with a low refractive index, light bends away from the normal. When light travels from a medium with a low refractive index to one with a high refractive index, light will bend towards the normal. When light travels in the same medium, the speed of light does not change, no refraction occurs, and the angle of incidence and
