a) The primary reason why the color redis used for danger signals is that redlight is scattered the least by air molecules. The effect of scattering is inversely related to the fourth power of the wavelength of a color. ... So redlight is able to travel the longest distance through fog, rain, and the alike.
b) This is because of the refraction of the light from the Sun by the Earth's atmosphere--the Earth's atmosphere bends the path of the light so that we see the Sun in a position slightly different from where it really is.
c) we cannot see an object clearly if it is placed very close to our eyes because the ray can not
reflact properly or the image formation can not occur
