Course Description
Overview
Learn about the apparent magnitude and absolute magnitude system in astronomy through this 17-minute video lecture. Explore the differences in star brightness, understanding how distance affects our perception of stellar luminosity. Prepare for the "Apparent and Absolute Magnitude" Lecture Tutorial by examining the challenges in determining true stellar brightness and comparing various stars' apparent magnitudes.
Syllabus
