There are 3 main layers of the Sun that we can see. They are the photosphere, the chromosphere and the corona. Together they make up the "atmosphere" of the Sun. The part of the Sun that glows (and that we see with the naked eye) is called the photosphere
Answer:
the wavelength of radiation emitted is
Explanation:
The energy of the Bohr's hydrogen atom can be expressed with the formula:
For n = 7:
For n = 4
The electron goes from the n = 7 to the n = 4, then :
Wavelength of the radiation emitted:
where;
hc = 1242 eV.nm
