Laser light traveling inside a slab of glass of index ofrefraction1.50 is incident on the surface with an angle ofincidence of60(degrees), as shown on the right.
a. sketch the reflected ray(if there is one), calculate the angleofreflection, and mark the angle of incidence and the angle ofreflection on the diagram.
b. sketch the refracted ray(if there is one), and mark the angleofrefraction on the diagram.
c. if either the reflected or refracted ray is missing,explainwhy.
5) 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 a 26.8° with the normal. What is the index of refraction of the glass?
6)
A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water into the 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
