1. The internal structure of precious opal makes it diffract light. 2. Lower frequencies diffract around large smooth obstacles such as hills more easily. 3. This means light is released as a particle and diffracts as a wave. 4. But audio diffracts as it passes through a doorway! 5. In modern fish, these diffract all wavelengths of light producing a silvery sheen. 6. Lead increases the weight of the glass and causes the glass to diffract light. 7. Crystals containing heavy atoms can diffract well, but also fluoresce themselves, causing interference. 8. Gratings diffract each energy or wavelength present in the incoming radiation in a different direction. 9. Neutrons diffract crystals similarly to X-rays and can be used for structural determination. 10. In X-ray diffraction a beam strikes a crystal and diffracts into many specific directions.
