🗑
|
||||
| atomic emission spectrum | the pattern formed when light passes through a prism or diffraction grating to separate it into the different frequencies of light it contains
🗑
|
||||
| ground satte | the lowest possible energy of an atom described by quantum mechanics
🗑
|
||||
| photons | a quantum of light a discrete bundle of electromagnetic energy that interacts with matter similarly to particles
