The energy of the photon can be calculated using the Rydberg formula. The transition from n=3 to n=2 emits a photon of energy approximately 1.89 eV.

The energy of a photon is given by E = hf. Using h = 6.63 x 10^-34 J.s, E = 6.63 x 10^-34 * 5 x 10^14 = 3.31 x 10^-19 J.

The energy of a photon is given by E = hν. Substituting the values gives E = 6.63 x 10^-34 J.s * 5 x 10^14 Hz = 3.31 x 10^-19 J.

The energy of a photon is given by E = hc/λ. Using h = 6.626 x 10^-34 J·s and c = 3 x 10^8 m/s, E = (6.626 x 10^-34)(3 x 10^8)/(500 x 10^-9) = 3.98 eV.

The energy of the ground state of a hydrogen atom is -13.6 eV.

The half-life is defined as the time taken for half of the radioactive sample to decay.

The half-life is defined as the time required for half of the radioactive substance to decay, which is given as 10 years.

The half-life of a radioactive substance is defined as the time taken for half of the substance to decay.

Nuclear fusion is the process that powers hydrogen bombs and is also the process that fuels stars, including the sun.

A black body is characterized by its ability to absorb all incident light, regardless of frequency or angle of incidence.

Alpha particles have a much greater mass than beta particles, which are electrons or positrons.

The main difference is that classical mechanics is deterministic, while quantum mechanics incorporates probability.

Nuclear fission involves the splitting of a heavy nucleus into smaller nuclei, while nuclear fusion involves the combining of light nuclei to form a heavier nucleus.

The main difference is that nuclear fusion combines light nuclei to form a heavier nucleus, while nuclear fission splits a heavy nucleus into lighter nuclei.

The main product of nuclear fusion in stars is helium.

The stability of atomic nuclei is primarily due to the strong nuclear force, which binds protons and neutrons together.

The stability of the electron orbits in an atom is primarily explained by quantum mechanics.

The stability of the nucleus is primarily due to the strong nuclear force, which binds protons and neutrons together.

In a P-type semiconductor, holes are the majority charge carriers.

The mass defect is the difference between the mass of the nucleus and the sum of the masses of its individual nucleons.

Maximum kinetic energy (K.E.) = hf - Φ = (6.626 x 10^-34 J·s)(8 x 10^14 Hz) - 3 eV = 5 eV.

Maximum kinetic energy (K.E.) = hν - Φ = (4.14 x 10^-15 eV·s)(8 x 10^14 Hz) - 3 eV = 5 eV.

Maximum kinetic energy (K.E.) = hν - Φ = (4.14 x 10^-15 eV·s)(8 x 10^14 Hz) - 3 eV = 5 eV.

The d-subshell can hold a maximum of 10 electrons.

A p subshell can hold a maximum of 6 electrons, as it has three orbitals each capable of holding 2 electrons.

The d subshell can hold a maximum of 10 electrons.

The f subshell can hold a maximum of 14 electrons (7 orbitals, each can hold 2).

The maximum number of electrons in an energy level is given by the formula 2n^2. For n=3, it is 2(3^2) = 18.

The maximum wavelength λ_max can be calculated using λ_max = hc/E, where E = 2.0 eV = 3.2 x 10^-19 J. Thus, λ_max = (6.63 x 10^-34 * 3 x 10^8) / (3.2 x 10^-19) = 620 nm.
