Hi, I love the color blue. Do you?
Yes, it is one of my favorite colors. Blue is used in a lot of art and decoration.
It reminds me of the ocean and sky. Why is that do you think?
Oh definitely, but the sky and sea are only blue because of an optical effect called Rayleigh scattering.
Rayleigh scattering? Please enlighten me as to what this is.
Rayleigh scattering
Rayleigh scattering ( ), named after the nineteenth-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime), the amount of scattering is inversely proportional to the fourth power of the wavelength.
Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts
, ‘That one take for me, for she is upright in my eyes.’” And the Baraita taught that the passage in “you shall stray after,” refers to promiscuity, which the prophets used as a metaphor for idol worship, as says, “The children of Israel again went astray after the Be’alim.”
It was taught in a Baraita that Rabbi Meir used to ask why specified blue from among all the colors for the fringes. Rabbi Meir taught that it was because blue resembles the color
