Since the extinction at short wavelengths is more sensitive to the increase of the mass of small grains than that at long wavelengths, the extinction curve becomes rather steeper.
Thus, the emission at higher frequencies (shorter wavelengths) is more intense, giving rise to its characteristic blue glow appearance, and it tends to be directionally emitted at an acute angle relative to the path of travel [ 7].
Blue wavelengths are more readily absorbed if the water contains average or abundant amounts of organic material.
When the effective thickness of the lithosphere is given, longer wavelengths are more easily compensated than the shorter ones.
Those blue wavelengths are more easily scattered by Earth's atmosphere than other colors, which would considerably increase the light pollution they ultimately contribute, bulb for bulb.
With a self-affine behavior, larger scale variations in h (small frequencies, long wavelengths) are more important than small scale (large frequencies, short wavelengths) variations.
However, researches on micro-motion targets, as a common type of object in the real world, are still very limited, although terahertz waves, due to their short wavelengths, are more sensitive to Doppler than microwaves and hence more suited for micro-Doppler imaging.
The earlier studies carried out by Hu et al. [6] reported that the shorter wavelengths were more sensitive to optical signature of oil; therefore, Landsat ETM+ data in spectral bands B1 (480 nm), B2 (560 nm), B3 (660 nm), B4 (825 nm) have been used in this study [6].
Changes of the characteristic absorption spectra of a given photosensitizer depend on the wavelength of the illumination light: shorter wavelengths are more effective than longer wavelengths [ 50].
