Unformatted text preview: not refracted? Tries 0/99 A green light is submerged 1.90 m beneath the surface of a liquid with an index of refraction 1.35. What is the radius of the circle from which light escapes from the liquid into the air above the surface? Tries 0/99 The refractive index of a transparent material can be deter-mined by measuring the critical angle when the solid is in air. If θ c = 41.5 ◦ what is the index of refraction of the material? Tries 0/99 A light ray strikes this material (from air) at an angle of 34.5 ◦ with respect to the normal of the surface. Calculate the angle of the re²ected ray (in degrees). Tries 0/99 Calculate the angle of the refracted ray (in degrees). Tries 0/99 Assume now that the light ray exits the material. It strikes the material-air boundary at an angle of 34.5 ◦ with respect to the normal. What is the angle of the refracted ray? Tries 0/99...
