Study Notes
Light and Vision
- Scattering of light by air molecules results in the blue color of the sky during the day.
- Light is the principal means of transmitting and receiving information to and from objects.
- Millions of colors on a television or computer monitor are formed by combining different intensities of red, green, and blue light.
- Clear vision for people who wear glasses or contact lenses depends on the correct refraction of light.
- The colors of a rainbow are caused by the refraction and dispersion of light as it passes through water droplets in the air.
- The red and orange colors of sunrises and sunsets result from the scattering of light by atmospheric particles.
