Electromagnetic Radiation. Electromagnetic waves perpendicular waves combing the electric and magnetic fields. . Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . the forces between (among) individual particles (atoms, ions, molecules); they are weak relative to . intramolecular. forces (i.e. covalent and ionic bonds within a compound). Intermolecular forces are increasingly significant in this order:. What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching.

Binder Check/Homework review. Electromagnetic Wave overview. Wave Overview. Spectrum Overview. Particle and Wave Properties. Speed equations. The Scottish physicist James Clerk Maxwell (1831–1879) was the first person to truly understand the fundamental nature of light. . He proved in 1865 that an electromagnetic disturbance should propagate in free space with a speed equal to that of light..
