When the wavelength is within the visible spectrum (the range of wavelengths humans can perceive, approximately from 390 nm to 700 nm), it is known as "visible light". Most light
Canadian Association for Physical Anthropology mission statement of CAPA/ACAP, as listed on the website, is as follows: "The Canadian Association of Physical Anthropology / L'Association Canadienne D'Anthropologie Physique is a learned society of international scholars and students whose aim is to promote and increase awareness and understanding of physical (biological) anthropology among its membership, as well as to supporting institutions and agencies and the public at large. Physical anthropologists study adaptation, variability and evolution in a biocultural context. Our members recognize and celebrate the geographic and temporal diversity and complexity of ancient and modern humankind, our hominid forebears and our nonhuman primate cousins and their
