How Bright is the Light?
Recommended for grades 6–12.
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 requires each of the following Vernier sensors and equipment (unless otherwise noted):
Additional Requirements
You may also need an interface and software for data collection. What do I need for data collection?
