Suppose you are using total internal reflection to make an efficient corner reflector - that is, a material shaped so that the light is reflected back towards its source. For example, each one of the prisms in the binocular shown is a corner reflector. θ = 32 ° If there is air outside and the incident angle at the first glass-air interface is 32° with respect to the normal, what must be the minimum index of refraction, nmin, of the...
Light is incident on the left face of an isosceles prism; with an apex angle of 49o, such that the light exiting the right face is parallel to its surface. What is the index of refraction of the prism, if the angle of incidence on the left face side is 28o to the normal of the face? Light is incident towards the apex.
A glass prism has a cross section of an isosceles triangle with α = 58.1°. A light beam is incident at an angle of θ = 49.5° and passes through the prism parallel to the base of the triangle as shown in the figure. What is the index of refraction of the glass? (Recall that the sum of all the internal angles of a triangle is 180°.)
In the figure, a ray is incident on one face of a triangular prism in air. The angle of incidence 0 = 35° is chosen so that the emerging light ray also makes the same angle with the normal to the other face. If the apex angle o is 52°, what is the index of refraction of the prism material? Number Units
