(Explanation): Use your formula E=hc/λ for this problem. replace λ with 502 x 10 ^(-9), since nanometers are 10 ^(-9) of a meter. Then replace h, or Planck's constant, with 6.626 x 10 ^(-34). C is light, or 3 x 10 ^8. You should plug into your calculator 6.626 x 10 ^ (-34) TIMES 3 x 10 ^ 8 DIVIDED BY 502 x 10 ^ (-9). You will get your answer.

Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
An emission or absorption line in a spectrum that arises when an electron moves between two energy levels in an atom. A jump to a higher level requires an input of energy, and produces a dark absorption line. A drop to a lower level releases energy, producing a bright emission line.

An absorption line is a line which corresponds to the absorption of electromagnetic radiation at a specific wavelength.

Absorption of energy at atom energy levels cause the line spectrum.

The electron has several possible energy levels. One of the lines corresponds to a transition from level 2 to level 1, another from level 3 to level 1, another from level 4 to level 1, another from level 3 to level 2, etc.
Do you mean a number line?The question you asked contains the answer. Every point on a number line corresponds to a number, and every number has a corresponding point on the number line.
