Light and Color
Grade 4 · Science · Waves and Information · Louisiana, USA
Lesson Summary
Light is a type of wave that you can see. White light is actually made up of all the colors of the rainbow.
Explanation
Light waves travel in straight lines and can move through empty space, which is how sunlight reaches Earth. When white light passes through a prism, it splits into all the colors of the rainbow: red, orange, yellow, green, blue, and violet. Objects appear to be a certain color because they reflect that color of light and absorb the rest. A red apple looks red because it reflects red light and absorbs the other colors.
