| 41. | Charles F . Brush in 1911 also proposed long wavelength radiation.
|
| 42. | Imagine two antennas that are separated by their wavelength / 3.
|
| 43. | Tape speed is a factor because of the shift in wavelengths.
|
| 44. | However they can nevertheless be practical receiving antennas for longer wavelengths.
|
| 45. | Furthermore, no lamp has a constant intensity at all wavelengths.
|
| 46. | The transmission efficiency of the monochromator also varies depending on wavelength.
|
| 47. | Spectral radiance expresses radiance as a function of frequency or wavelength.
|
| 48. | Cones are most sensitive to light at wavelengths around 420 nm.
|
| 49. | Terrestrial radiation is emitted at much longer wavelengths than solar radiation.
|
| 50. | Multiple images may be recorded sequentially at different narrow wavelength bands.
