• Clear tape

• Metal foil

• Glass sheets

• Colored paper

What is the primary function of a polarizer?

• To magnify light

• To filter light based on its orientation

• To absorb light

• To reflect light

Which type of light is most commonly found in nature?

What is the Haidinger's brush?

• A type of polarized light

• A pattern seen on LCD screens

• A method to measure light intensity

• A tool for painting

What causes the colorful patterns when using tape with polarizers?

• The tape absorbs certain colors

• The tape magnifies the light

• The tape reflects light

• The tape twists the polarization of light

How does the second polarizing filter affect the colors seen?
