Question

What evidence can you find in the diagram that light leaving the sun passes through cooler hydrogen gas? Use the letters in the diagram to specify features of the spectra to which you refer in your answer. OPTION 1: Absorption lines at specific wavelengths (A, B, C) OPTION 2: Emission lines at specific wavelengths (D, E, F) OPTION 3: Continuum spectrum across all wavelengths (G, H, I) OPTION 4: Absence of spectral lines in certain regions (J, K, L)

Answer 1

The absorption lines (A, B, C) in the spectrum are evidence of light passing through cooler hydrogen gas as they represent frequencies absorbed by hydrogen atoms in the Sun's cooler outer layer. None of the above answer is correct.

Step-by-step explanation:

The evidence that light leaving the sun passes through cooler hydrogen gas can be seen in the absorption lines at specific wavelengths (A, B, C).

These black lines in the spectrum indicate specific frequencies of light that have been absorbed by the cooler hydrogen atoms, which correspond to the electrons in the hydrogen atoms jumping to higher energy levels.

The remaining continuum spectrum (G, H, I) shows the wavelengths that have not been absorbed and continue to be emitted by the Sun.

None of the above answer is correct.
