Question

select the correct answer.
light incident on a polarizer is then passed through a second polarizer. if the polarizer and the analyzer are perpendicular to each other, what can you say about the light waves emerging from the second polarizer?
a. the light waves are partially blocked.
b. the light waves are completely blocked.
c. the light waves are of the same intensity as the incident light.
d. the light waves have three times the intensity of the incident light.
e. the light waves have half the intensity of the incident light.

Explanation:

Para la polarización de la luz, cuando un polarizador (primer polarizador) y un analizador (segundo polarizador) están perpendiculares entre sí, la luz que pasa a través del primer polarizador (ya polarizada) no tendrá componentes de su campo eléctrico que puedan pasar a través del segundo polarizador, ya que sus ejes de polarización son perpendiculares. Por lo tanto, la luz es completamente bloqueada.

Answer:

B. The light waves are completely blocked.
