F: Fundamental Laws of Light

Question 1

The ration of the light
absorbed by a material to the light falling upon it is called

Answer 1

absorption

Question 2

When light falls upon an opaque material, it is reflected.
When the material has a polished surface, the light will be
reflected at an angle equal to the angle of incidence.

Answer 2

specular reflection

Question 3

When the material has an
unpolished surface, however, the reflected light is spread in
all directions by multiple reflections on the unpolished
surface.

Answer 3

diffuse reflection

Question 4

The ratio of
reflected to incident light is called

Answer 4

reflectance

Question 5

Upon translucent material,
however, such as plastic, the emerging light will
spread in all directions.

Answer 5

diffuse transmission

Question 6

When the reduce light rays are distributed in all
directions with maximum intensity normal to the surface.

Answer 6

Diffusion

Question 7

The property of the material to change direction of light
at the interface between two different materials, such as
air and glass.

Answer 7

Refraction

Question 8

The phenomenon wherein the waves vibrates only in one
place.

Answer 8

Polarization
