Module #7: Atomic Structure Flashcards
Isotopes
Atoms with the same number of protons but different numbers of neutrons
Mass Number
The total number of neutrons and protons in an atom
Isotopic enrichment
Adjusting the percentage of an isotope in a substance
Particle/Wave Duality Theory
The theory that light sometimes behaves as a particle and sometimes behaves as a wave.
Wavelength
The distance between the crests (or troughs) of a wave
Amplitude
A measures of the height of the crests or the depths of the trough on a wave
Physical Constant
A measurable quantity in nature that does not change
Frequency
The number of wave crests (or trough) that pass a given point each second
Equation for relating properties of light
F = c / λ F = Frequency, c = speed of light, λ = wavelength
As a light wave’s frequency increases it’s energy __?
As a light wave’s frequency increases, its energy increases.
As a light wave’s wavelength increases, its energy __?
As a light wave’s wavelength increases, its energy decreases.
Light is analogous to __?
Electromagnetic Radiation
