Line Spectrum Flashcards
What is the nature of the emission spectra
Emission of light due to electron transitions from higher to lower energy levels
What is the nature of the line spectra
Specific wavelengths of light emitted or absorbed by atoms
What are the types of emission spectra
Continuous and line spectrum
What are the types of line spectra
Emission lines (bright) & absorption lines (dark)
What is the appearance of the emission spectra
A continuous spectrum shows all wavelengths
What is the appearance of the line spectra
Bright lights or dark lights against a continuous background
What is an example of the emission spectra
Sunlight
What is an example of the line spectra
Hydrogen gas
What do lines in emission spectrum correspond to
Energy emitted as a photon in transitions from higher to lower energy levels
What do lines in the absorption spectrum correspond to
Energy absorbed from a photon in order for an electron to make a transition to a higher energy level
