    merchandise A is blue, so it does not mirror the purple (magenta) part of the spectrum. under a magenta easy it is going to look black. merchandise B is yellow, this is, it includes no blue or organic purple aspects, shone with magenta it is going to look yellow, because of the fact magenta is the complementary of blue, it includes purple, green, and yellow aspects. The index of refraction n, frequently, is greater for greater densities. because of the fact the cost of the easy is inversely proportional to n, the better the density the smaller the cost.
