The video tutorial explains the concept of albedo, a reflection coefficient used in meteorology. It compares the albedo of different objects, such as white and black surfaces, and illustrates how light reflection affects albedo. The tutorial also provides examples of albedo ranges for various surfaces, like oceans and fresh snow, highlighting that most substances fall between zero and one in terms of albedo.
