Understanding Colors and Light

The video explores the concept of color, explaining that it originates from light, which is a wave and part of the electromagnetic spectrum known as the visible spectrum. Colors are determined by the frequency of light, with red having the lowest frequency and violet the highest. When light passes through a prism, it separates into the visible spectrum colors. The color we perceive is the one reflected by an object, while other colors are absorbed. Practical examples include how a red car reflects red and absorbs other colors, turning them into heat. The video concludes with a reminder about the importance of kindness.
