Electromagnetic Radiation Pt.1
Explain what Wavelength, Frequency, and Amplitude is
Frequency: # of waves per second (Energy and frequency have a direct relationship)
Amplitude: Height of waves(Determines brightness, high=brighter/low=dimmer)
__ increases as _____ increases
KE, Frequency
What is the lowest allowable energy level called?
Ground state
True/False: Electrons can be in two different states at the same time
True
True or false: you can observe an electrons nature both as a particle and a wave
False
List colors in order of longest wavelength to shortest
Red,orange,yellow,green,blue,indigo,violet.
# of electrons emitted _____ with intensity
Increases
What is it called when electrons absorb energy and jumps to a higher energy level?
Excited state
What did Erwin Schrodinger's experiment prove?
Quantum strangeness does not transfer to the macroscopic world.
Name the Principle: The more accurately we know the position of an electron, the less accurately we can know its velocity.
Heisenberg's Uncertainty Principle
What did the double slit experiment prove?
Light behaves as a wave
List radiation wavelengths from low energy to high energy
Radio, Microwave, Infrared, Visible Light, Ultraviolet, X-ray, Gamma Ray
When does UV, Visible, and IR light start at?
UV: n=1
Visible: n=2
IR: n=3
How was electrons shown to act as a wave?
Unobserved electrons go through two slits and interfere with themselves.
If an electron's velocity increases, what happens to the wavelength?
It shortens
What did the Photoelectric effect prove?
light also behaves as a particle
Difference between constructive and destructive interference?
Destructive:Waves out of phase produce a wave with no amplitude
When an atom absorbs energy, it often remits the energy as ____
Light
An electron's wavelength is proportional to its amount of ___
Kinetic Energy

What is diffraction?
The amount of energy absorbed determines the type of ____ radiation emitted
EM (Electromagnetic)
Any experiment designed to observe the electron as it travels through the slits results in the detection of an electron as a ___
Particle
Why does the uncertainty principle make it impossible to predict a trajectory for the electron?
Because it's impossible to predict the trajectory of an electron.
