First Years Guide to Ace Astronomy: A Study Guide

written by Lily Lavender

This book is intended for all who need a quick study reference guide for ASTR-101. It has a glossary of terms & its appropriate meanings for the entire course. Each chapter is based on a lesson; where it won't go into grave detail, but will give you the necessary components to study for upcoming tests & assignments. This does not include mid-term & final exams. All detailed information about each topic is in your official lessons with the Professor. DO NOT COPY AS IT IS PLAGIARISM!

Lesson Six: How to Find the A.M.E. Components Study Guide

Chapter 7

Angular Size, Phase, & Optical Albedo


Arcminutes are the apostrophe (') & arcseconds are the quotation mark ("). The smallest & biggest values are split by dashes (-). On the Von Rheticus telescope, a button labeled S is for angular size. In red, o means degrees. If the object appears to not be round, it uses its largest dimension from its angular size. A comet with an angular length of two degrees, thirty-five arcminutes, & twenty-eight arcseconds will be seen in red as 2o35'28". Phase is calculated by angular length & width. It is then divided by the length. Another button on the Von Rheticus telescope is labeled A, which is the albedo. In red, a number between zero & one will be seen. Start from the lowest magnifying power & increase it until you see the lightest or darkest part of the body.


Interference & Magical Albedo


You must calculate the angular split between the object & objects that are around it in order to know the interference. Dr. Mansour found that magical albedo is similar to optical albedo. A rocky surface displays half of magic, light, water, & ice. It slashes magical albedo & soaks up the magic from the Sun. The A button on the new telescope model will show the A.M.E. Quotient. It will show the intensity of magic from a celestial body.


Fun Facts
The first mundane telescope was created in 1608; seventy years after the Von Rheticus telescope has resolving power that is equal to a 12 cm Muggle telescope.
The Hubble telescope has more resolving power & the Keck telescope has adaptive optics.
The movement of the planets & the calculation of the planets from the Sun were studied by Von Rheticus. He calculated by using Earth's distance from the Sun.
Venus is the biggest; 6.8 times when close & far from Earth.
