WebTo measure the refractive index of glass or plastic, we will use a semicircular block. 1. Place the semicircular block on a piece of paper, somewhere around the middle of the sheet, and draw carefully around its edge. 2. On your drawing, measure the length of the straight edge and place a mark at its centre. 3. Web2. Shine the light ray through the glass block. 3. Use crosses to mark the path of the ray. 4. Join up crosses with a ruler. 5. Draw on a normal where the ray enters the glass block. 6. Measure the angle of incidence and the angle of refraction and add these to …
WebActivity 3: Snell's law Snell's law states that when light goes from medium 1 to medium 2, the angles relative to the normal are related by the refraction indices in each medium: n, sino, =ny sin, In this activity, we will observe the refraction of the beam in a block of glass, for different angles, and use the data to determine the index of …
