Question

absorption spectra explain please​

Answer 1

Explanation:

Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. ... The transmitted energy can be used to calculate the absorption.

Answer 2

Answer:

an electromagnetic spectrum in which a decrease in intensity of radiation at specific wavelengths

Explanation:

or ranges of wavelengths characteristic of an absorbing substance (as chlorophyll) is manifested especially as a pattern of dark lines or bands — compare emission spectrum.
