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.
