Blackbody Radiation
Photoelectric Effect
Atomic Spectra
Bohr’s Model
de Broglie waves
100
An object that absorbs all incident re-emits it, depending on the temperature.
What is a blackbody?
100
The potential difference at which the current stops flowing.
What is stopping potential?
100
Refers to the observation and analysis of the spectral lines that correspond to a definite wavelength and frequency.
What is emissions spectroscopy?
100
deltaE = hv
How would you describe the emitted or absorbed radiation during an electron transmission between energy levels of a hydrogen atom?
100
λ = h/p
What is de Broglie’s equation?
200
A blackbody’s temperature increases as radiation shifts to shorter wavelengths
Why does a blackbody get hotter when you shift from red to blue?
200
A value specific to a metal that is the minimum energy required to release an electron through the photoelectric effect.
What is the work function?
200
Emission Spectra
Absorption Spectra
Continuous Spectra
What are the 3 types of spectra?
200
Niels
What is Bohr’s first name?
200
The wavelength associated with the particle is based on its momentum.
What is the concept of de Broglie waves?
300
Describes the relationship between temperature and the wavelength where it emit radiation most intensely.
What is Wien’s Displacement Law?
300
6.626x10^(-34)J/s
What is Planck’s constant?
300
This series of spectral lines is visible when electrons transition to n=2 energy level in hydrogen atoms.
What is the Balmer series?
300
Planetary Model
What is another term for Bohr’s model
300
March 19, 1987
When did de Broglie die?
400
This problem in classical physics couldn’t explain why the intensity of radiation from a blackbody increases infinitely at high frequencies.
What is the ultraviolet catastrophe?
400
The electrons emitted by materials when undergoing the photoelectric effect.
What are photoelectrons?
400
Light spectrum with the wavelengths of 740 nm - 380 nm
What is the visible light spectrum.?
400
These two states are wherein an atom is in any state that is time-independent, and the other is where an atom is at its most stable configuration
What are the stationary and ground state of an atom?
400
This idea suggests that particles such as electrons can exhibit wavelike properties, as confirmed by electron diffraction experiments.
What is wave particle duality?
500
1900-1901
When was blackbody radiation‘s concepts solidified by Planck?
500
This suggests that it is not just the vibrational energy of the atoms in a blackbody that is quantized but light itself is also quantized.
What is Einstein’s model?
500
What is the Rhyzen Balmer equation?
500
This mathematical expression is used to calculate the energy of an electron in any given energy level of a hydrogen atom.
What is the Bohr energy equation?
500
E=mc^2=mv^2=hv; since real particles do not travel at the speed of light, we substitute c with v
=> mv^2 = hv/λ; therefore λ = hv/mv^2 = h/mv
How do you derive de Broglie’s wavelength formula?
