in IR region, _____ is used as light source
tungsten
in UV region, ____ is used as light source
deutereum
it is the negative logarithm of transmittance
absorbance
what is the energy called for the electromagnetic spectrum
radiant energy
it is defined as the complete system of energy propagated in a wave form
electromagnetic spectrum (EMS)
fundamental law of spectrophotometry where it states the relationship between sample concentration and absorbance
beer’s law
distance between one wave from another
wavelength
it is the reciprocal of wavelength
