Diffusion<span> is the spread of particles through random motion from regions of high concentration to regions of lower concentration. Because </span>diffusion<span> works without barriers, when </span>smoke<span> is emitted into the air, it can easily travel to surrounding areas. hope this can help you ^_^ </span>
Answer:
It looks yellow because that is the only (major) color reflected.
Visible spectra is from about 4000-7000 Angstroms (10^-10 m).
Red are longer wavelengths and blue are the shorter wavelengths.
The Sodium doublet (yellow) occurs around 5900 Angstroms.
F has direct relation with a
then doubling F cause acc. to get double i:e 6×2=12
