In photometers, the readings of the specimen are initially obtained in the form of which of the following parameters?
A. Transmittance B. Absorption C. Wavelengths D. Volume
Explanation: In photometers, the reading is initially obtained in the form of transmittance as some radiation is absorbed by the sample and the rest of the beam is transmitted. This transmitted beam is measured by the detector.
