Topic 4 - Waves - Absorption Flashcards
1
Q
What happens when the frequency of light matches the energy levels of electrons?
A
The light will be absorbed by the electrons and not reemitted
This process leads to the specific absorption of that frequency of light.
2
Q
What occurs to absorbed light over time?
A
It will be reemitted over time as heat
This process indicates that the energy from the absorbed light is transformed into thermal energy.
3
Q
What does it mean when a material appears green?
A
Only green light has been reflected
This implies that all other frequencies in visible light have been absorbed by the material.
4
Q
Fill in the blank: If a material absorbs a particular frequency of light, that frequency has been _______.
A
