Differentiate between intrinsic and extrinsic absorption
Answers
Answer:
Intrinsic Absorption: Caused by the interaction with one or more components of the glass Occurs when photon interacts with an electron in the valence band & excites it to a higher energy level near the UV region. Extrinsic Absorption: Also called impurity absorption.
Intrinsic absorption is due to internal fiber properties while extrinsic absorption is due to the impurities in a material.
Explanation:
Intrinsic absorption is due to internal fiber properties while extrinsic absorption is due to the impurities in a material.
Intrinsic absorption is sure when there are no impurities in the material. Intrinsic absorption allow minimal absorption.Extrinsic absorption is due to impurities due to iron, chromium, etc traces into the material. it is caused when the transition of this material takes place from one energy level to another energy level
