Across
- 2. One of the seven spectral colors; It is the most common color seen in the natural world thanks to photosynthesis.
- 4. The branch of physics that studies the behavior and properties of light.
- 6. Optical phenomenon witnessed in weather following a rain event, with sunlight's interaction with airborne water.
- 9. Films such as Snow White and the Seven Dwarfs (1937), Gone with the Wind (1939), and The Wizard of Oz (1939) were among the first major American films to be presented using this process to show film in color.
- 11. Colors such as pink and magenta are examples of these sort of colors that can only be produced by a mix of multiple wavelengths together.
- 13. A transparent optical element with flat, polished surfaces that are designed to refract light.
- 15. One of the seven spectral colors; more common names associated with this color include teal and aquamarine.
- 17. The inability to distinguish between certain colors, principally between reds and greens, and occasionally blues.
- 19. One of the seven spectral colors; It shares its name with a fruit and is a considered a secondary color, being a mix of two other spectral colors.
- 20. Colors containing only one of the seven major wavelengths are also called pure colors.
- 22. One of the seven spectral colors; It is the darkest of the three primary colors, the rarest color to find from amongst natural sources, and also the first major color to be created artificially using chemical manipulation.
- 24. The first color film to be successfully mass-marketed for both still and motion picture cameras; Is also the title to a 1973 Paul Simon song.
Down
- 1. One of the seven spectral colors; It is the brightest of the three primary colors.
- 3. Issac Newton famously determined that color is a property of this and not of the object as seen.
- 5. The lightest color; It fully reflect and scatter all the visible wavelengths of light.
- 7. One of two sets of cells within the human eye; contain photo pigments, or color-detecting molecules, needed to recognize different colors.
- 8. Humans' exposure to these kinds of optical rays can develop an increased risk of skin cancer.
- 10. Working similarly to what brings sound through one's radio, these bands of electromagnetic radiation help your eyes determine the perceived color an object appears to be.
- 12. Invisible to the human eye, these wavelengths can heat surfaces that absorb them.
- 14. One of the seven spectral colors; At between 625 to 740 nanometers, it has the longest wavelength of any color within the visible spectrum. Is also the easiest dye color to reproduce from natural source materials.
- 16. One of the seven spectral colors; At between 380 and 435 nanometers, it has the shortest wavelength of any color within the visible spectrum. Shares its name with a flower.
- 18. The total range of colors that the human eye can distinguish.
- 21. One of two sets of cells within the human eye; when activated, one does not see color, just shades of gray.
- 23. The darkest color; It is the result of the complete absence or complete absorption of visible light.
