You can see them so must reflect the light. That means that you can see beyond the light passing through it so that it would be a shadow. The darkness of shadow depends on it 'the density? s, l? should be an object behind it to throw a shadow over.

No. To a rainbow you need a clear passage through the spherical droplets of water. The crystal ice are not spherical.

Result No. of rainbows by a double reflection of waves in a clear drop of liquid water. The ice has a refractive index different and does not contribute to the rainbows. A phenomenon that you could see that it is caused by a crystal of ice is a guidacarta around the sun or the moon - this is called the guidacarta 22 degrees.

A rainbow requires spherical drops of water, which aren 't present in the tail of a comet. On land, you can also get various forms of effects of colored light by ice crystals in the atmosphere, but that probably won 't happen in the comet tail of one or the other, for two reasons. The first is that the ice crystals that cause the sundogs and other such phenomena are the atmospheric processes that aren 't present in a comet. The second is that these crystals are all uniform align the right way to cause the colored reflections. On earth, this is caused by the combined effects of gravity and atmosphere while the ice crystals fall through the atmosphere. Although suitable crystals of ice could form in comet 'tail of s, I don' t think that there is something there that could cause such an alignment.

This site should give points for these additional allowances excellent questions! I don 't know, but I suspect that it may be possible to see a small part the arch of a rainbow in accordance with the geometry of observation and the nature of the vapor of ice. A rainbow is seen when the light reflected by water droplets. The light is reflected and spread out in the colors within each droplet. A similar effect could occur if the vapor of Vater in the tail of the comet particles in the condensate with the appropriate figure, the sizes, properties and internal characteristics of the surface. A guidacarta is probably more likely. A bright star seen through a tail could produce just one.

Yes, if the light passes through the very small micro droplets that behave like microprisms.
