| 21. | The wavelength selective mirror is a periodically structured diffraction grating with high reflectivity.
|
| 22. | So the reflectivity of rain coming from melted snow is only slightly higher.
|
| 23. | Increased reflectivity decreases both absorption and emission of radiation.
|
| 24. | Reflectivities greater than 99.5 % are routinely achieved in dielectric mirrors.
|
| 25. | Synthetic Aperture Radar determines the 3-D reflectivity from measured SAR data.
|
| 26. | In general, the useful range compromise is 100 150 km for reflectivity.
|
| 27. | The reflectivity has large variations in a short distance.
|
| 28. | The reflectivity of the mirrors is around 90 %.
|
| 29. | The proportion of reflected radiation is the object's reflectivity or albedo.
|
| 30. | The reflectivity image is just one type of image produced by a radar.
