Final answer:

The relative population of two states in a He-Ne laser can be calculated using the equation P(1) / P(0) = e^(-ΔE / kT), where ΔE is the energy difference between the states and T is the temperature. However, the specific values needed to determine the ratio are not provided in the question.

Step-by-step explanation:

The relative population of two states in a He-Ne laser can be determined by comparing the probabilities of the energy states involved. In this case, the energy states being compared are n = 1 and n = 0.

The ratio of the probabilities of these states can be calculated using the equation P(1) / P(0) = e^(-ΔE / kT), where ΔE is the energy difference between the two states, k is Boltzmann's constant, and T is the temperature. However, the specific values of ΔE and T are not provided in the question, so it is not possible to determine the exact relative population ratio.

The relative population of two states in a He-Ne laser, producing light with a wavelength of 632.8 nm, depends on the energy difference between these states.

Using the Boltzmann distribution formula, which involves factors like the Planck constant, speed of light, and temperature (assumed as 300 K), the ratio of populations can be calculated. The exact value will depend on the specific higher energy level chosen for comparison.

Comparing the result to the given options (A, B, C, D), the closest ratio indicates the relative population relationship, providing insights into the quantum mechanics governing the laser's operation.
