| 41. | Weber and Fechner conducted research on differences in light intensity and the perceived difference in weight.
|
| 42. | They are often found on reef flats exposed to high light intensity and intermittently strong currents.
|
| 43. | Light therapy involves at least 20 minutes of exposure to 3000 to 10000 lux light intensity.
|
| 44. | It was determined that the leakage light intensity is proportional to the intensity in the waveguide.
|
| 45. | Again the applied light intensities can be quite low ( some 100 W / cm?).
|
| 46. | The shade provided by the larger trees reduces water temperatures and light intensity from ultraviolet light.
|
| 47. | :What we perceive when flicker fusion kicks in is more or less the average light intensity.
|
| 48. | Essential factors affecting food availability are the light intensity and moisture content of the hammock habitat.
|
| 49. | The areas of decreased light intensity look like shadows and the turbulence makes tham wave around.
|
| 50. | Then, a series of lenses bring the image into focus, while a diaphragm controls the light intensity.
