Example 1

Problem description

A beam of natural light shines from the air onto a flat glass （ See the picture 2-3-6）, Let the angle of incidence be equal to the Brewster angle , On the interface 2 Reflected light of （　　）.
A 、 It's natural light
B 、 It is completely polarized light and the vibration direction of the light vector is perpendicular to the incident plane
C 、 It is completely polarized light and the vibration direction of the light vector is parallel to the incident plane
D 、 It's partially polarized light

answer

The above questions should be B Options .

analysis

When light is incident at Brewster angle , All the components parallel to the paper surface in the reflected light disappear , Only the weight perpendicular to the paper .

So we should choose B Options .

Example 2

Problem description

A beam of natural light shines from the air onto a flat glass , Let the angle of incidence be equal to the Brewster angle , Then the reflected light is （　　）.
A 、 Natural light
B 、 Partially polarized light
C 、 Completely polarized light
D 、 Circularly polarized light

answer

The above questions should be C Options .
