What is the difference between spontaneous and stimulated emission?
Spontaneous Emission: An atom emits a photon randomly. Stimulated Emission: An incoming photon triggers an atom to emit an identical photon.
What is the difference between photon absorption and emission?
Absorption: Atom gains energy, electron jumps to higher level. Emission: Atom loses energy, electron drops to lower level.
What is the effect of an electron transitioning between energy levels?
Emission or absorption of a photon with energy equal to the energy difference.
What is the effect of radioactive decay?
Transformation of an unstable nucleus into a more stable nucleus, accompanied by the emission of particles and energy.
What is the effect of increasing a particle's momentum on its de Broglie wavelength?
The de Broglie wavelength decreases.
What is the effect of doubling the length of the box on the energy of the ground state?
The energy of the ground state decreases.
What is the process of radioactive decay?
An unstable nucleus emits particles and energy, transforming into a different nucleus. This is a probabilistic process.
What are the steps of photon absorption?
A photon interacts with an atom. If the photon's energy matches the energy difference between two energy levels, the atom absorbs the photon. The electron jumps to a higher energy level.
What are the steps of photon emission?
An electron in an excited state drops to a lower energy level. The atom emits a photon with energy equal to the energy difference between the two levels. This can occur spontaneously or be stimulated by an incoming photon.
