IR Detections and Color of the Visible Light

Expose the detecting material to the intense heat lamp again in an dark room. Before exposing the material to visible light, cover one-half of the detecting material with the colored transparent plastic. While holding this transparency in place, expose the IR card to visible light.

Return to the dark. Then, activate the remote control and describe the results. Repeat the experiment until you have results for, at least, red, green, and blue transparencies. Summerize your results and conclusions.

Summary of Experiments

From your observations:

1. Speculate about other sources of energy that might be involved in the emission of visible light from the card. Explain your conclusions using your observations.
   
2. Speculate why the light emitted by the card decreases after a period of time in the dark room even though the IR light from the remote control is kept on it.
