Pigments rely on colors of light that are

• added.

• subtracted.

• reflected.

• refracted.

The primary pigments are _______________ the primary colors.

• complementary to

• associated with

• the inverse of

• unrelated to

_________________ is the alignment of electro-magnetic waves in such a way that the vibrations of the electric fields in each of the waves are parallel to each other.

• Diffused light

• Linear polarization

• Unpolarized light

• Scattered light

If a light source is emitting electric fields that are oscillating in random directions, the light is said to be

• polarized.

• diffused.

• unpolarized.

• scattered.

The direction in which electric fields are polarized by transmission

• is determined by the arrangement of the atoms or molecules in the crystal.

• occurs along the transmission axis.

• results in linear polarization.

• all options

The line along which light is polarized is called the ______________ of that substance.

• primary axis

• transmission axis

• rotational axis

• polarized axis
