Light and Color Concepts Assessment

This video tutorial explores how different colors of light affect the appearance of objects, focusing on a red rose under various lighting conditions. It explains the role of rod and cone cells in the human eye in color perception and includes interactive questions to reinforce learning. The lesson concludes with a discussion on how animals see in the dark.
