Name :__________________________ Modeling Light Intensity with a Rational Function From a Distance The activity illustrates a natural phenomenon. As you increase the distance from a light source, the perceived intensity of the illumination will decrease. To investigate the phenomenon, we will: Use a CBL to help collect realistic data points Create a scatter plot of the data points Use the data points to determine an algebraic function that models the data Use the algebraic function to answer some questions 1. Use a CBL to help collect data points Set up the CBL to collect data: o Plug the light-sensor in to CH1. o Plug the calculator in to the CBL. o Turn on the calculator. o Set-up the CBL application: Press APPS button. Scroll down to EasyData and press Enter. The calculator should start displaying readings of the light intensity measured by the sensor. Collect Data: o Place a meter stick next to the light sensor. (Either place both on the floor or put two level desks together) o Adjust the flashlight so you have a fine beam.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
