Electromagnetic Radiation
Frequency, wavelength, and source are all used to identify types of this
Electromagnetic radiation
The smallest amount of energy that a wavelength can possess
quantum
Famous for E = mc2 but actually contributed a lot more than that to quantum physics
Einstein
Thomson's model that looked like a dessert
Plum Pudding Model
The subatomic particle orbits the nucleus of an atom
electron
The angle of reflection = the angle of incidence
The Law of Reflection
photoelectric effect
He described the behavior of electric and magnetic fields, unifying electricity, magnetism, and light into a single theory
Maxwell
These particles in the cathode ray experiments were originally called "corpuscules"
electrons
the charge of this subatomic particle is 0
neutron
Planck's formula
E = hf = hc/λ
The equation that relates the work function to the threshold frequency
W = hf0
Coined the Uncertainty Principle
Heisenberg
Millikan was able to calculate this based on the oil drop experiments
the elementary unit of charge, e, the charge on a proton
the charge and mass of an electron
-1e, 9.11 x 10-31 kg
The equation used for finding the angle of diffraction
sin θn = nλ /d (will also accept λ = xd/nl)
The laws of conservation of momentum and conservation of energy informed this effect that calculated the direction and wavelength of an X-ray photon
Compton Effect (or λ = h/mc (1-cosθ))
He conducted the famous oil-drop experiment, which determined the elementary electric charge and provided evidence for the quantization of electric charge
Millikan
Wasn't accurate for atoms that had two or more electrons
atoms that have the same number of protons but different numbers of neutrons
isotopes
When light travels from air into water and the angle of incidence is 30 degrees and the index of refraction of water is 1.33, the angle of refraction is this
22.3
The wavelength of an electron moving at 1.00 x 104 m/s is
7.28 x 10-8 m or 72.8 nm
His principle in wave theory states that every point on a wavefront serves as a source of secondary wavelets that spread out in all directions, explaining wave propagation phenomena such as diffraction
Huygens
The flaw in the planetary model of the atom by Rutherford
According to EMR laws and the planetary model, the electron should continuously radiate energy and spiral into the nucleus
the mass of two protons and two neutrons
approximately 6.695×10−27 kg
