AST 111 Lecture Notes - Lecture 7: Special Relativity, Energy Flux, Kelvin
Document Summary
Started class with the matching exercise: renaissance astronomers. Light travels through empty space at a speed of 300,000 km/s. Newton"s prisms colors were inherent to light, not produced by the prism he thought light was a set of particles: newton"s enemy huygens advocated the wave model, today we recognize the wave particle duality motion of light. Are there different kinds of wave? a wave is a disturbance that transfers energy. 2 kinds of waves the motion is transverse to the application of energy: 1. Longitudal wave the wave moves along the slinky as the colors go through roy g biv, the temperature of those objects goes up: based on the freezing point at 32 degrees and boiling at 212 degrees. Celsius: freezing at 0 degrees and 100 degrees. A theoretical understanding of light came from maxwell"s work on electricity and magnetism. He showed that electric and magnetic fields travel together through space in the.
