The EM Spectrum
A spectrum of wavelengths that comprise the various types of electromagnetic radiation.
What is the electromagnetic spectrum?
This type of spectrum contains no gaps or breaks within its range.
What is continuous spectrum?
The process whereby an element is identified based on the wavelength of line emission spectrum.
What is atomic spectra?
The probability of finding an electron in a region of space
What is the square of the wavefunction?
This type of electromagnetic radiation has the highest frequency on the EM spectrum.
What are gamma rays?
A spectrum that appears as dark lines on a coloured background
What is absorption spectrum?
The physical constant that relates to the electromagnetic spectra of an atom.
What is the Rydberg constant?
This principle states that the position and momentum of a particle cannot be simultaneously found.
What is Heisenberg's uncertainty principle?
Joule (J), named after physicist James Prescott Joule
What is the SI unit for energy?
A spectrum emitted when a pure gaseous element is subjected to an electrical discharge.
What is emission spectrum?
The spectral line series that is in the infrared radiation region of EMS and occupies n = 3 as its ground-state.
What is Paschen?
+½ and -½
What are the possible spin values for an electron?
These two properties are inversely related
What is the relationship between energy and wavelength?
This experiment causes electrons in metal atoms to get excited and jump to a higher orbital before returning to ground state, emitting photons of energy and producing colour which can be used to identify the metal.
What is a flame test?
The case where energy gaps become negligible and the kinetic energy of the electron exceeds the electric potential energy.
What is continuum?
This particular quantum number accounts for the shape of the orbital.
What is the angular momentum quantum number?
c - vλ
How is wavelength related to frequency?
Ranges from 400nm to 700nm.
What is the range of visible light?
Determine the final n in a hydrogen atom transition if the electron starts at the fourth energy level and emits a photon with a wavelength of 486 nm.
n = 2
This equation accounted for relativistic effects in the quantum mechanical model of the atom.
What is the Dirac equation?
