AST 101 Lecture Notes - Lecture 2: Electromagnetism, Electric Field, Fundamental Interaction
Document Summary
Wave disturbance that carries energy without the motion of material from one. Disturbance often in the form of a repeating pattern: pattern is what moves and place to another carries energy. Wave properties: place or how many cycles pass by per second". Number of times the wave pattern will repeat (per second) if you stay at a fixed. Speed of light is written as c . All forms of light travel at this same speed in vacuum. One of the fundamental forces of nature is gravity; another is the electromagnetic. 1) the electric force: most particles have a positive/negative charge to force. Draw imaginary arrows describing how strong electric or magnetic forces are and in what direction they point: we call these the electric field" or magnetic field". Creating electric and magnetic fields periodic way too there will be a wave in the field. When electric charges move in a periodic way, the electric field will move in a.
