Electromagnetic Energy and Electron Energy Levels ch 2 Flashcards
The electrons in atoms obtain energy from being
_______ and release energy as
at different _________ which give rise to different
colors.
1-heated
2-wavelengths
wavelength : the distance between identical points
The colors that we can see are only part of the
___________
electromagnetic spectrum
aa lik tro mag na tik/ spak trim
electro mag netic spectrum
The visible light spectrum
is the segment of the electromagnetic spectrum that the human eye can view
Photon with large wavelength are_____energy
photon with small wavelength are ________energy
1-lower
2-higher
wavelength is referred to as __________
electromagnetic spectrum
photon
foh tan
photon
is particle of light
Light energy moves in an ________ pattern and we
commonly represent it in the form of waves.
oscillating=تذبذب
ass ill ateing
osc ill ating
light does not ________energy
give off
parts of wave :
1-frequency
2-amplitude
3-wavelength
frequency
the number of waves peak in period of time
unit would be Hz or s-1
Hir tiz
Hz
Amplitude
aam plit ood=السعه
Amp li tude
the height of repreasentive wave from the baseline
wavelength
the distance from one peak to the next wave
what is the relationship between wavelength and frequency :
Wavelength x Frequency = Speed of light (in a vacuum)
blue light such as sunlight
higher energy and frequency
and has short wavelengths.
Red light
lower energy
low frequency
higher wavelength
