Chapter 11 Flashcards
Length of a wave (measured in nm); the distance between peaks
Wavelength (T)
Energy transmitted from one place to another by light in the form of waves
Electromagnetic radiation
The vertical distance from the middle of the wave to the crest/trough
Amplitude
The top of a wave
Peak/crest
The number of waves that pass through a specific point in a given amount of time (measured in waves/sec or hertz (Hz)
Frequency (V)
Waves of electromagnetic radiation from short to long
Gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves, radio waves
Light shining on a metal emits electrons
Photoelectric effect
Packets of light (quantum); particles of electromagnetic radiation (have no mass)
Photons
Planck’s equation
E=h•V
H= 6.626•10^-34
Speed of light equation
C=T•V
C=3.0•10^8
Rainbow colors within a given range
Continuous spectrum (visible spectrum)
Consists of several distinct lines of color each with its own frequency; each element has one
Bright line spectrum (line emission spectrum)
Finite quantity of energy that can be gained or lost by an atom
Quantum
Lowest energy state
Ground state
Atom has higher potential energy than at ground state
Excited state
Describes mathematically the wave properties of electrons and other very small particles
Quantum Theory
