Radiations are absorbed in_______________?
Correct answer: A. Spectrophotometer method
- A. Spectrophotometer method
- B. Dilatometric method
- C. Optical relation method
- D. Refractometric method
Explanation
A spectrophotometer measures how much radiation a substance absorbs at selected wavelengths, usually by comparing incident and transmitted intensities. Dilatometric and refractometric methods measure volume-related and refractive properties, not absorption directly. Students may choose d because refraction also involves light, but refraction is different from absorption.

About Planck's Quantum Theory
Planck's quantum theory states that energy is emitted or absorbed in discrete packets called quanta, with each packet having energy E = hν. It covers the meaning of Planck's constant, the relationship between frequency and wavelength, and how quantisation differs from the classical continuous model of energy.
