In summary, the wavelength of emission for the H-atom is 656.3 nanometers (nm) and is calculated using the Rydberg formula. The energy and wavelength of emission for the H-atom are inversely proportional, and the wavelength for the H-atom is unique and cannot be compared to other elements. Its significance lies in providing information about the energy levels and structure of the atom and allowing for identification and study of the element through emission spectra.

1. What is the wavelength of emission for the H-atom?

The wavelength of emission for the H-atom is 656.3 nanometers (nm).

2. How is the wavelength of emission for the H-atom calculated?

The wavelength of emission for the H-atom is calculated using the Rydberg formula, which is λ = R(1/n₁² - 1/n₂²), where R is the Rydberg constant (1.097 x 10⁷ m^-1) and n₁ and n₂ are the initial and final energy levels of the electron.

3. What is the relationship between energy and wavelength for the H-atom?

The energy and wavelength of emission for the H-atom are inversely proportional. This means that as the energy level of the electron increases, the wavelength of emission decreases.

4. How does the wavelength of emission for the H-atom compare to other elements?

The wavelength of emission for the H-atom is unique and cannot be compared to other elements. Each element has its own unique set of energy levels and therefore its own unique wavelength of emission.

5. What is the significance of the wavelength of emission for the H-atom?

The wavelength of emission for the H-atom is significant because it provides valuable information about the energy levels and structure of the atom. It also allows us to identify and study the element in various forms, such as in emission spectra.
