Question

1-Specular reflection of light is...


a-reflection from a smooth surface where the reflected rays are parallel to each other.

b-reflection from a smooth surface where the reflected rays are always parallel to the incoming rays.

c-reflection in random directions because the surface is rough


2-The law of reflection states that...


a-The angle of reflection is twice the angle of incidence.

b-the angle of reflection is 180 degrees different than the incident angle.

c-The light waves always reflects directly back towards the source.

d-The angle of reflection equals the angle of incidence.


3-A real material has an index of refraction that is greater than 1.  This means that light that travels through the material...


a-Travels faster than the speed of light.

b-travels slower than the speed of light in a vacuum.

c-Travels the same speed as if it was in a vacuum.

d-Completely reflects and does not enter the material.
