Listing 10 of 65 questions
shows a ray of light that enters a semicircular glass block at A. At B, some of the light is reflected and some light leaves the glass and travels along the surface. 0.10 m B A 41° glass block State the name of the angle of incidence marked 41°. Rays of light are incident at B with different angles of incidence. On a, the angle i1 is less than 41°. Draw the path taken by the ray of light after B. On b, the angle i2 is greater than 41°. Draw the path taken by the ray of light after B. B B i2 i1 a b The speed of light in the glass block is 2.0 × 108 m / s. The diameter of the glass block is 0.10 m. Calculate the time taken for the light to travel from A to B. time =
