Larger waves carry more energy. Electricity is light.
Radio waves require higher energy than X-rays.
Students will be able to state the relationship between a color's wavelength and the amount of energy it uses. From the results, students may infer that energy is contained in the entire electromagnetic spectrum. Students may try to feel the heat from the diodes. Psychomotor domain -In a high school setting, students may be given instructions and asked to build the electric circuit demonstrating these energy relationships. At LSU, teachers attending the workshop will be told to build a circuit using the available parts at their tables.
