Question 8 A light ray incident on a block of glass makes an incident angle of 50.0° with the normal to the surface. The refracted ray in the block makes an 31.9° with the normal. What is the index of refraction of the glass?
1.4500
Between 1.38 and 1.52
Question 9
A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water into air) would bend away from the normal to the medium surface. When the refracted ray is parallel to the boundary of the medium, θ2 = 90°. The incident angle, θ1, becomes θc, called the
conjugate angle
Cauchy angle
classic angle
critical angle
