Suppose we detect red photons at 656 nanometers emitted by electrons dropping from the n=3 to n=2 orbital in hydrogen. The hydrogen is in an interstellar cloud at 5,000K. If the cloud were heated to 10,000 K, what would be the wavelength of the photons emitted by the transition?

656 nanometers

Explanation:

Using Rydberg Expression to approach this question, we have the expression given as:

where;

λ = wavelength

R = Rydberg Constant

= initial stage of the energy levels

= final stage of the energy levels

Now, from above expression, it is seen that the wavelength( λ) of the hydrogen spectrum is clearly independent in relation to the temperature. As such; if the cloud is heated to 10,000 k; the wavelength of the photons emitted by the transition will still remain to be 656 nanometers.

what type of charge does it have? negative

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
