| 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.
