Form of energy that exhibits wavelike characteristics and travels through space.
all forms of electromagnetic radiation
x-rays, to UV rays, to infared light, to micro waves to radio waves.
the number of waves that pass a given point in a specific time, usually one second. (waves/second
speed of light Equation
(frequency is inversely proportional to wavelength)
the emission of electrons from a metal when light shines on the metal
frequency determines electrons emitted*
equation for Energy
relationship between a quantum of energy and frequency
Energy is proportional to frequency
particle of electromagnetic radiation having zero mass and carrying a quantum of energy
Energy of Photon = (h)frequency
Dual wave-particle nature
einstein introduced that light can sometimes be in the form of a wave or as a particle
state at which the atom has a higher potential energy that its grounded state
(electron gives off energy in form of electromagentic radiation from excited state to get back to ground state)
Energy of photon emitted
the energy of a photon emitted is equal to the difference in energy between the atoms' initial state and it's final state.
energy must be added to an electron of lower energy to get to a higher energy level
energy of absorbed or emitted photon corresponds to a particular frequency of emitted light
heisenburg uncertainty principle
states that it is impossible to determine simultaneously both the position and velocity of an electron or any other atomic particle
mathematically describes the wave properties of electrons and other very small particles
three dimensional region around the nucleus that indicates the probable location of an electron
specify the properties of atomic orbitals and the properties of electrons in orbitals
