FT IR Spectroscopy What does the Michelson interferometer do? Selectively filter certain wavelengths from a beam of I.R. radiation Split a polychromatic beam of radiation into its component wavelengths None of these Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector Selectively filter certain wavelengths from a beam of I.R. radiation Split a polychromatic beam of radiation into its component wavelengths None of these Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector ANSWER DOWNLOAD EXAMIANS APP
