How Does Light Create a Colorful Pattern?

What happens when light passes through a triangular hole with green and red light bulbs?

Does it create a specific color pattern on the screen?

Answer:

The resulting pattern on the screen will have a mix of green and red colors.

When light passes through the triangular hole in a mask positioned between a small green light bulb and a small red light bulb, it creates a colorful pattern on the screen. In this scenario, the green light bulb projects a green triangle on the screen, and the red light bulb projects a red triangle. When these two colored light beams overlap, they combine to form new colors.

This phenomenon is known as color addition or additive color mixing. When different colored lights overlap, they interact to create a blend of colors rather than a clear separation of one color over another. The intensity of each color in the resulting pattern depends on the brightness of the respective light bulbs.

Therefore, the pattern on the screen will not be a solid color but a visually interesting mix of green and red, demonstrating the principles of additive color mixing. This creates a dynamic and colorful display that showcases how light can interact to create new colors and patterns.
