Final answer:
The experimental procedure involves passing electric current through a tube containing hydrogen gas, which emits pink light. The emitted light is spread out to reveal four individual frequencies. Each element has its own unique emission spectrum.
Step-by-step explanation:
The experimental procedure for determining the emission spectra and electronic structure of atoms, specifically the hydrogen spectrum, involves passing electric current through a tube containing hydrogen gas. This causes the hydrogen gas to emit light, which appears pink to our eyes. When the emitted light is spread out, it is found to consist of four individual frequencies or colors. Each element has its own unique emission spectrum.
By observing the emission spectrum of an element, scientists can determine the wavelengths of light that are emitted when its atoms transition from higher-energy states to lower-energy states. This information is crucial for understanding the electronic structure of atoms and how energy levels relate to the emission of light.
In the case of hydrogen, the emission spectrum is composed of four specific frequencies or colors, which are characteristic of hydrogen atoms. These frequencies can be used to calculate the wavelength of the emitted light using a specific formula. The hydrogen spectrum has been observed in different regions of the electromagnetic spectrum, including infrared (IR), visible, and ultraviolet (UV) regions.
