Given a scientific passage and an answer, generate a question for the given answer.
One example: Passage: A frameshift mutation is a deletion or insertion of one or more nucleotides that changes the reading frame of the base sequence. Deletions remove nucleotides, and insertions add nucleotides. Consider the following sequence of bases in RNA:. Answer: nucleotides.
Solution is here: A frameshift mutation is a deletion or insertion of one or more of what that changes the reading frame of the base sequence?
Explanation: The science passage defines frame mutation and the main compoment here is nucleotides. Hence the generated question is apt.

Now, solve this: Passage: 27.8 Polarization Polarization is the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave. EM waves are transverse waves that may be polarized. The direction of polarization is defined to be the direction parallel to the electric field of the EM wave. Unpolarized light is composed of many rays having random polarization directions. Light can be polarized by passing it through a polarizing filter or other polarizing material. The intensity I of polarized light after passing through a polarizing filter is I = I 0 cos 2 , where I 0 is the original intensity and is the angle between the direction of polarization and the axis of the filter. Polarization is also produced by reflection. Brewster's law states that reflected light will be completely polarized at the angle of reflection b , known as Brewster's angle, given by a statement known as Brewster's law: reflected light travel and. Answer: unpolarized light
Solution:
What type of light is composed of many rays having random polarization directions?
