Question
Dichorism means:
✓
Answer
- Selective absorption of one of the polarised component.
Dichromism is the selective absorption of one orthogonal polarization component of an incident beam over the other. this phenomenon is due to anisotropy of the material, with one polarization component experiencing preferential absorption.
