Line spectra from all regions of the electromagnetic spectrum, including the paschen series of infrared lines for hydrogen, are used by astronomers to identify elements present in the atmospheres of stars. calculate the wavelength of the photon emitted when the hydrogen atom undergoes a transition from n = 5 to n = 3. (r = 2.179 x 10-18 j r = 1.096776 x 10^7 m-1) a. 205.1 nm b. 384.6 nm c. 683.8 nm d. 1282 nm e. > 1500 nm

The correct answer is option D.

Explanation:

Using Rydberg's Equation for hydrogen atom:

Where,

= Wave number

= Wavelength of radiation

= Rydberg's Constant

= Higher energy level

= Lower energy level

We have:

()

The wavelength of the photon emitted when the hydrogen atom undergoes a transition from n = 5 to n = 3 is 1282 nm.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
