Is the presumption that light behaves strictly as a wave sufficient for describing all of its properties? Is the presumption that light behaves strictly as a particle sufficient for describing all of its properties? What is meant by the wave/particle duality of light?
Please answer in one hundred fifty words or more
An aqueous solution of copper sulfate was found to have an absorbance of 0.168 at 265 nm when measured in a cuvette with a path-length of 0.500cm. If the absorptivity of the transition is 11.5m^2/mol what is the copper concentration in
