ASTR 1101 Chapter : Comparative Planetology
Document Summary
What is a wave: a wave is how energy moves from one place to another, a wavelength is measured crest to crest, tells you energy, frequency, everything you need to know about the wave. Other wave properties: waves can add (interference, waves meet at crest; you get a big wave, waves meat at crest and trough; they cancel out. Types of waves: mechanical waves, sound waves, water waves, seismic waves, electromagnetic radiation, radio, microwave, optical light, x-rays, mechanical waves require mediums but electromagnetic waves do not. Increase the radius so it shrinks and moves from infrared to optical band. Which of the following stars is the coldest: d (the one with the lowest graph) Which one is giving off more of a particular wavelength? (also, a fair question) If red and yellow are the colors, then yellow is the bluer one: so a had shortest peak wavelength so it is hotter and therefore bluer than the rest.
