Polaroid Filters

Figure from experiment 24 from Physical Science with Vernier

Introduction

Polarized light is light in which the waves vibrate in a specific direction. It can be produced by passing light through a special “polarizing” filter. Sunglasses cut down glare on a bright sunny day. Some sunglasses have lenses made of polarizing material. The light waves that vibrate in the same plane as the polarizing material can pass through, but other waves are reflected or absorbed. In this experiment, you will use a computer-interfaced Light Sensor to study the transmission of light through Polaroid filters.

Objectives

In this experiment, you will

  • Measure the intensity of transmitted light.
  • Study the transmission of light by Polaroid filters.
