Bohr’s Model of the Hydrogen Atom
When the absorption spectrum of hydrogen at room temperature is analyzed, absorption lines for the Lyman series are found, but none are found for the Balmer series. What does this tell us about the energy state of most hydrogen atoms at room temperature?
● Overview of the Cosmological Argument: ○ While the ontological argument is a priori (independent of experience), the cosmological argument is a poste riori (takes personal experience into account). It claims that the observable world is ultimately explained by something transcendent: God. ○ Modal Terms: ■ Necessary thing: one whose nonexistence is impossible ■ Contingent thing: one whose existence a nd nonexistence are possible/impossible. ■ Possible thing: one whose existence is either certain or possible. ■ Impossible thing: one whose existence is impossible the opposite of a necessary thing. ■ Philosophers do not agree on which modal term is applied for each thing in the world because there is no agreedupon criteria for what is “possible” and what is “impossible.” ○ The cosmological argument asserts that there m ust be one necessary thing or being, and that would be God. However, this is a twostep process: one must prove that 1) there must be one necessary being and 2) that necessary being is God. ■ Saint Thomas of Aquinas reaches this conclusion without addressing these two issues. However, this criticism of Aquinas is unfounded because he is simply stating a historical fact: men before, such as Aristotle, have reached the c
