Answer: Option (e) is the correct answer.
Explanation:
A solar spectrum is defined as the range of electromagnetic energy emitted by the Sun. Range of this spectrum mainly lies in ultraviolet, infrared and visible region.
This spectrum is extending from 290 nm in longer wavelengths of UV region to over 3200 nm in the far infrared.
A solar spectrum consists of 67 elements and some of which are hydrogen (71%), helium (27%), oxygen, nitrogen and carbon are about 1.5% and the rest 0.5% contains iron, silicon, neon, magnesium and sulfur.
Therefore, we can conclude that many, many elements, ranging from light gases like hydrogen and helium to metals like iron, gold, and chromium can be found in a solar spectrum (meaning that the Sun’s atmosphere must contain these elements).
