Chemistry
A sample tube consisted of atomic hydrogen in their ground state. A student illuminated the atoms with monochromatic light, that is, light of a single wavelength. If only two separate emission lines in the visible region are observed, what is the wavelength (or wavelengths) of the incident radiation?

Ответ:
The wavelength of the monochromatic light is 486.2 nm.
Explanation:
The illumination of the hydrogen atom by the monochromatic light causes an absorption of energy by its electrons which causes an excitation. After a period, the particle de-excites (decays) losing the absorbed energy and falls back to its initial state releasing the energy in the form of a photon. This photon can be observed as a colored light of the Balmer series.
From Rydberg's expression,
1/λ=−R(
−
)
The transition of the electron is from n = 2 to 4, so that;
1/λ = R (
-
)
= 1.097 x
(

)
1/λ = 2056875
So that,
λ =![\frac{1}{2056875}](/tpl/images/0679/6211/5c009.png)
= 4.8617 x
m
The wavelength of the monochromatic light is 486.2 nm.
Ответ:
These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. ... All of the cell's organelles must work together to keep the cell healthy.
Hope this helps!
