🌞 Properties of Light and the Electromagnetic Spectrum
This quiz explores the nature of light as an electromagnetic wave, the electromagnetic spectrum, and how light interacts with matter. You'll discover the relationship between frequency and wavelength, identify different types of electromagnetic radiation, and understand real-world applications in everyday technology. **What you'll learn:** - Light is an electromagnetic wave that travels through space - The electromagnetic spectrum ranges from radio waves to gamma rays - Visible light is just one small part of the full spectrum - Wave properties like frequency and wavelength are inversely related - Light reflects and refracts when it interacts with different materials
