Concepts for 7.1-7.5 Flashcards
Understand conceptual aspects of sections 7.1-7.5
Wave
Vibrating disturbance by which energy is transmitted
Wavelength
The distance between identical points on successive waves
Frequency
Number of waves that pass through a particular point in one second
Amplitude
Vertical distance from the midline of a wave to the peak or trough
Electromagnetic wave
Electric field component and a magnetic field component
Maxwll’s theory
Mathematical description of the general behavior of light.
Electromagnetic radiation
Emission and transmission of energy in the form of electromagnetic waves
Electromagnetic waves
Speed of light
Quantum
Smallest quantity of energy that can be emitted (or absorbed) in the form of electromagnetic radiation
Photoelectric effect
Electrons are ejected from the surface of certain metals exposed to light of at least a certain minimum frequency (threshold frequency)
Photons
Particles of light
Atomic emission Spectra
Either continuous or line spectra of radiation emitted by substances
Line spectra
Light emission only at specific wavelengths
Color
Tells us the wavelength, frequency, and energy being emitted
Ground state (ground level)
Lowest energy state of a system
