A beam of light is traveling inside a glass block that is surrounded by air. The beam strikes the upper surface of the block at an angle of incidence of 6, which exceeds the critical angle so the beam experiences total internal reflection at the upper surface. The beam refracts out of the block (well, some is also reflected but we don't care about that) on the right side, where the angle between the normal and the beam in the airis 8. Air has an index of refraction of 1.00. @ Part (a) o Homework Unanswered Due Apr9th, 12:15 PM The value of 8 is 70.0 and the distance x shown on the picture is 18.0 cm.

You keep the incident angles the same, so the only way to do this is to replace the glass with another material that has a different index of refraction. What is the minimum index of refraction necessary so the light experiences total internal reflection at the right side of the block? (For reference, diamond has one of the highest indices of refraction, at 2.4, which might give you an idea how realistic it might be to achieve the goal here.)
