ASTR 1102 Study Guide - Final Guide: Chromatic Aberration, Hydrostatic Equilibrium, Naked Eye
Document Summary
Scientific method: question, observe, explain, predict, test. 1 degree = 60 minute = 60 seconds. Angular size depends on distance (d) and linear size (d) Extinction: dimming by the atmosphere (absorption by smoke and dust and scattering by moisture) X = airmass mag(x) = magnitude at x mag(x) = mag(0) + (k x) mag(0) = magnitude outside atmosphere k = extinction value (depends on site) " opposition is the prime viewing time for superior planets. " white light is just a mixture of all of the colors. It depends on how it"s studied. luminiferous aether: allows light to propagate through space light is self-propagating which means it creates its own medium. Einstein described light in discrete quanta (photons) which explains the photo electric effect. = wavlength (nm) c = speed of light (m/s) E = energy (ev) h = planck"s constant (ev s) hc = 1240 ev s / nm.
