Primary Colors of Light
Primary Colors of Light
Red, green, and blue light are the primary colors detected by our eyes. Combining two of these colors creates a secondary color. Combining all three produces white light.
How Objects Appear Colored
How Objects Appear Colored
Objects absorb certain wavelengths of light and reflect others, determining their perceived color. For example, a blue object appears blue because it reflects blue light and absorbs the other colors.
How a Prism Creates a Spectrum
How a Prism Creates a Spectrum
When white light passes through a prism, it separates into different colors because each color bends at a different angle. Violet light bends the most, while red light bends the least.

Study Notes
Colour and Light
- Our eyes detect three colours of light: red, green, and blue
- Adding these colours together (in certain combinations) creates other colours
- Coloured objects absorb some colours of light and reflect others
- A prism can split white light into a spectrum of colours
- The spectrum shows different colours of light, with red having the lowest frequency, and violet having the highest
- Objects appear different colours due to the light they reflect
- When a white object is illuminated by red light and viewed through a green filter, it will appear black because the green filter only allows green light to pass through, and the white object reflects all colours but absorbs red.
- When a green object is illuminated by white light and viewed through a green filter, it will appear green because the object reflects green light and the filter only allows green light to pass through.
- A red ball illuminated by yellow light will appear red because yellow light is a combination of red and green, and the red ball absorbs the green light and reflects the red.
