A light ray is incident on a reflecting surface. If the light ray makes an angle of 25 degrees, with respect to normal what is the angle made by the reflected ray relative to the normal?
The light ray that makes the angle θ2 is the reflected ray from the diagram.
3. The laws of reflection can be used to show how an image appears behind a mirror and it can be used to determine the position of the image. True/False.
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
