Optical Phenomena Flashcards
1
Q
Photoelectric Effect
A
Process whereby electrons are ejected from a metal surface when light of suitable frequency is incident on that surface
2
Q
Threshold Frequency
A
Minimum frequency of light needed to emit electrons from a certain metal surface
3
Q
Work Function
A
The minimum energy that an electron in the metal needs to be emitted from the metal surface
4
Q
Atomic Absorption Spectrum
A
Is formed when certain frequencies of electromagnetic radiation passing through a substance is absorbed
5
Q
Atomic Emission Spectrum
A
Is formed when certain frequencies of electromagnetic radiation are emitted due to an atom making a transition from a higher energy state to a lower energy state
