- This is the result of an experiment in a spectrophotometer. please explain how the 595 nm was obtained and what is the implication of that result? thanksarrow_forwardTrue or False 1. Photodiode arrays are devices within the instrument that help amplify the signal of a sample. 2. Atomic spectroscopy requires the atomization of a sample, which involves nebulization and eventually volatilization to form an elemental vapor. 3. Organic compounds are normally analyzed in atomic spectroscopy despite their small electronic transition range.arrow_forwardhow the principle of spectrophotometric experiments?
