GenChem Making Light Efficiently Today’s Agenda: Review understanding of light. Develop the day’s problem. Perform the first challenge: determine wavelength values for colors. Perform the second challenge: measure the light emitted by an incandescent light bulb. Analyze results: determine the efficiency of the incandescent light bulb. Perform the final challenge: measure the light emitted by a compact fluorescent light source. Analyze results: determine the amount of light and energy generated at different wavelengths. Secondary analysis: compare light generated to power required. 5 th Class
