Polarization of Light starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Polarization of Light.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A beam of light is incident at Brewster's angle on a glass surface. What is the angle between the reflected and refracted rays?
A beam of plane polarized light of intensity I₀ passes through a polaroid. If the angle between the light's polarization and the polaroid's axis is 30°, what is the transmitted intensity?
A beam of unpolarized light passes through two polaroids. The first polaroid's axis is vertical, and the second is at 60° to the vertical. What fraction of the original intensity is transmitted?
A polaroid is rotated through 360° in a beam of plane polarized light. The intensity of transmitted light will:
