Calculate the reflectance for specific conditions. For example, say that a polished gold surface subjected to direct radiation with a wavelength of 480 nanometers reflects about 60 percent of that radiation. In this case, the reflectance would be q(y) = (Gr(y)/Gi(y))^2 = .6^2 = .36, or about 36 percent.
axial skeleton - the part of the skeleton that includes the skull and spinal column and sternum and ribs. breastbone, sternum - the flat bone that articulates with the clavicles and the first seven pairs of ribs. skull - the bony skeleton of the head of vertebrates.
the major function of the axial skeleton is to establish the long axis of the body and to protect structures that it encloses; the general function of the appendicular skeleton is to allow us mobility for propulsion and manipulation of our environment.
