Electromagnetic Radiation and Atomic Spectra Flashcards
1
Q
What is the order of the electromagnetic spectrum in increasing wavelength?
A
Gamma Rays, X-rays, UV, Visible, Infrared, Microwave, Radio
2
Q
As wavelength increases, frequency….
A
Decreases
3
Q
As frequency increases, wavelength….
A
Decreases
4
Q
As frequency increases, energy….
A
Also increases
5
Q
How does a line appear on an emission spectra?
A
Electrons move to higher energy levels and become excited. They can then drop back down to lower energy levels releasing a photon of energy which corresponds to specific wavelength.
6
Q
Why are there multiple lines on the emission spectra?
A
Because there are multiple electron transitions taking place.
