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 entire skeletal system can be divided into two parts, axial and appendicular. There are, in total, 300 bones in a newborn, but some of them fuse together and finally, there are, in total, 206 bones left in an adult. The axial axis There are 80 bones in the axial part of the skeletal system. The axial axis consists of cranial bones facial bones ear ossicles hyoid bone vertebrae ribcage sternum The appendicular axis The remaining 126 bones belong to this category.
