Light Energy Properties Worksheet for Grade 8 Science Review.

📚 Topic Summary

Light energy is a form of electromagnetic radiation that makes it possible for us to see. It travels in waves and exhibits several properties, including reflection, refraction, and absorption. Understanding these properties is crucial for comprehending how light interacts with different materials and our environment. Visible light is only a small part of the electromagnetic spectrum, which also includes radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
