Answer:
The answer is opt- d
Velocity of light
Explanation:
Velocity of mild isn't always similar to the intense spectral strains
A spectral line is a darkish or vivid line in an in any other case uniform and non-stop spectrum, due to emission or absorption of mild in a slim frequency range, as compared with the close by frequencies. Spectral strains are regularly used to pick out atoms and molecules.
A vivid line spectrum is created whilst a beam of mild passes via an analyte pattern wherein a few wavelengths of the mild are absorbed via way of means of the atoms withinside the pattern; therefore, the electrons in the ones atoms get to an excited state. These vivid strains display that electrons have jumped from better electricity degree to decrease electricity degree. When electron jumps from a few better orbit, the electricity launched withinside the from of photon could be greater,and we get a brighter line. Thus in hydrogen spectrum a few strains are brighter than others
