The questions for this assignment are to be submitted through crowdmark i) for case (a) to (c) derive the merical formula for the energy using electron volts as a unit. do both cases for (c). also convert the boltzman constant to units of evk1. i want to have common units for the energies, while starting from the comonly used expressions this will get the point across that energies are very different ii) for cases (a) to (d), at room temperature (300k), calculate the ratio of finst excited pground ii) for cases (a) to (d), at room temperature (300k), calculate the lowest index r (representing n, , or v) of the excited state for whiclh ground such that its contribution starts to be negligible (or small at least). use the following equations to simplify this question: pground pground
