GenChem Week 5 Making Light Efficiently Today’s Agenda: ± Review understanding of light. ± Develop the day’s problem. ± Perform the first challenge: measure the light emitted by an incandescent light bulb. ± Analyze results: determine the amount of light generated at different wavelengths. Determine the amount of energy generated at different wavelengths. ± Perform the final challenge: measure the light emitted by other light sources. ± Analyze results: determine the amount of light and energy generated at different wavelengths. ± Secondary analysis: compare light generated to power required. ± Final analysis: draw conclusions.
