Spectrum:
(a). Different colors observed when the white light was dispersed through the prism
(b). The changing of light intensity as a function of frequency
Spectroscopy: Study of spectrum, to identify substances

In
the past, the
word spectrum was introduced into the area of optics at
first, referring to the range of colors
observed when white light was dispersed
through a prism.
Soon after that, a spectral density or
spectrum is also known as the term referred to a plot of light intensity or power as a
function of frequency or wavelength.
Spectroscopy is the study of spectrum, study of the interaction between radiation ,
for identifying the substances through the spectrum emitted from or absorbed by
them.
