Quantum Mechanical Model of The Atom Flashcards
(33 cards)
The energy emitted in the form of waves having an oscillating electric field component that is perpendicular to magnetic field component.
Electromagnetic radiation
Highest point of a wave (points W and Y)
Crest or Peak
Lowest point of a wave (point X and Z)
Trough
Distance between a grass and a trough in the midline of the wave (thick dashed line)
Amplitude
1/2 the vertical distance from a crest to the nearest trough
Amplitude
Related to the intensity (I) of a wave (radiant power per unit area)
Amplitude
Distance between two successive crests for two consecutive troughs
Wavelength
Number of wave cycles propagating per second
Frequency
Number of crest or number of trout passing through a certain point per second
Frequency
Inversely proportional to the wavelength.
Frequency
Time it takes for one cycle of a wave to pass through a point.
Period (T)
Reciprocal of the frequency
Period (T)
Number of cycles per unit distance
Wavenumber
Reciprocal of wavelength
Yours when waves combine. It can be constructive or destructive.
Interference
Results with with combine in phase.
Constructive Interference
Occurs when two waves combine out of phase
Destructive interference
Bending of waves when they pass it through a slip or aperture.
Diffraction
Process of “bouncing back” of a beam of light waves after it strikes the surface.
Reflection
The bending of waves when they pass from one on other medium.
Refraction
The transfer of energy of waves in to matter. This manifested by the lowering of intensity after the wave passes through an object.
Absorption
Occurs when light is absorbed by matter, and it is re-emitted in different directions. This phenomenon can be observed in daytime light.
Scattering
Classical physics claims that the intensity of light be committed by a heated body called a____________ increase towards infinity as temperature increased
Blackbody
The limitation of the classical model at lower wavelength is called the______________.
Ultraviolet catastrophe
