1.1 Electromagnetic Radiation and Atom Spectra Flashcards
C =Fh
C=Speed of light, F=Frequency, H(lamda)=Wavelength
The wavelength of visible light is expressed in
Nanometers
A photon carries
a quantum of energy
In emission spectroscopy higher temps are used to
excite electrons within the atom and as electrons drop to lower energy levels photos are emitted
As frequency increases
Wavelength decreases
Grannys eX Used to Vist In Melrose Regularly
Gamma rays, X-rays,Ultraviolet,Visible,Infrared,Microwaves, Radiowaves
Visible light is between
Infrared and ultraviolet (400nm-700nm)
E=hf
Where H is Planck’s constant
E=Lhf
Avogadro’s constant and only use L if it’s in moles
How is a line produced in an emission spectrum?
The excited electrons moves up to a higher energy level and then drops back down to a lower energy level. This releases a photon of energy which correspond to a specific wavelength
What do different line mean?
There are multiple electron transitions
