How Bright is the Light?

Figure from experiment 25 from Physical Science with Vernier

Introduction

You may have noticed that a light appears to be brighter when you are close to it, and dimmer when you are farther away. In this experiment, you will use a computer-interfaced Light Sensor to measure light intensity as you study the relationship between light intensity and distance.

Objectives

In this experiment, you will

  • Measure light intensity.
  • Graph and analyze data.
  • Make conclusions about the relationship between light intensity and distance.

Sensors and Equipment

This experiment features the following Vernier sensors and equipment.

Option 1

Option 2

Additional Requirements

You may also need an interface and software for data collection. What do I need for data collection?
