What is speed?
speed of a wave is the wavelength (in meters) multiplied by its frequency in reciprocal seconds
What is speed dependent on?
frequency and wavelength
What are the units?
wavelength in meters
frequency in hertz (reciprocal seconds)
what is the equation for speed?
wavelength x frequency = speed
What can we do with coalesced radiation?
break it down into components
What is the shortest wavelength?
What is the longest wavelength?
Why do we get a raninbow?
each wavelength acts diffrently with particle size
True or False:
Elements give us all the same color
Elements can give us a different color
What does atomic spectra result from?
result from excited atoms emitting light
What does line spectra result from?
result from electron transitions between specific energy levels
How Different Colors Actually Occur?
On the line spectra, what does each line represent?
a unique wavelength of radiation
What happens when an electron falls from a high energy shell to a low energy shell?
it emits electromagnetic energy whose frequency corresponds to the energy difference between orbitals
What do we categorize the levels as?
On the periodic table, where is n found?
on the side going vertically down
