absorbance caused by:
◉100% reflectance is set with an opaque film called a white
reference. Answer: Reflectometry does not follow Beers-Law but the
relationship between concentration and reflectance can be
described by a logistic formula. Name the statement that best
describes Reflectometry?

◉Nephelometry. Answer: Measuring light scattered at 90* to the
incident light for maximum sensitivity to small particles which cause
cloudiness in drinking water.
