Across
- 5. The prism bends the light and causes the colors to ___________ from each other. This happens because each color has a different wavelength.
- 7. Light is a form of _______ called the electromagnetic spectrum.
- 8. Each color _________ at a slightly different angle depending on the wavelength of the color. This word means change direction.
- 14. Ultraviolet (UV) radiation is part of the _________ light spectrum that reaches earth from the sun. It cannot be seen but it can cause skin aging and skin cancer.
- 16. Light moves through space as a wave. We show light as a _____ organized by how long or short the waves are.
- 17. Our sun produces more ___________ light than any other color.
- 20. Sometimes, color gives us information about ________________.
- 22. Isaac Newton's experiment in 1665 showed that a prism bends _________ light.
- 24. This is the type of wavelength between microwave and visible light? See the diagram.
Down
- 1. Other wavelengths (other than visible) are too large or too small for our eyes to _________.
- 2. Blue is closer to violet in the rainbow and has shorter waves than red light. This also means that blue light has more ________ than red light, and blue flames have the hottest temperature in a fire.
- 3. __________ rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum.
- 4. Violet is at one end of the rainbow because it has the shortest ____________________.
- 6. If the sun's surface were a cooler 3,000 degrees Celsius it would look reddish like the star _________.
- 9. waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum.
- 10. Wavelength tells us how much energy a specific type of light has. The light we can see is somewhere in the _______ of the spectrum.
- 11. The flames that look red have the longest wavelength, which means they have the ________ energy. While all fire is hot, red flames have cooler temperatures.
- 12. If the sun were a hotter 12,000 degrees Celsius, it would look _______ like the star Rigel.
- 13. Visible light ranges from 380 ______ to 700 nanometers.
- 15. A _______ is a piece of clear glass that looks like a triangle or a pyramid. The smooth sides and sharp angles affect how light passes through it.
- 18. ________ is at the other end of the rainbow because it has the longest wavelength.
- 19. Visible light has a _________ of colors.
- 21. Visible light is the part of the ___________________ spectrum that you're most familiar with. We see it because our eyes pick up the wavelengths of visible light.
- 23. The ______ light that passes through a prism looks like a rainbow on the other side.
