Light and Color Experiments: Electromagnetic Spectrum, Using Spectroscopes

Are your students curious about UV and Infrared light but are unsure what they are? How does the light from a neon sign compare with that from an incandescent or fluorescent bulb? How can you study and compare different types of light. This is a simple experiment that will help you dig into this material.
