Question

what is a light spectra called when you slow it down with a prism (so you can see the lines)?
absorption spectra
emission spectra
continuous spectra

Explanation:

• Absorption spectra show dark lines where light is absorbed.
• Emission spectra show bright lines as atoms emit light at specific wavelengths.
• Continuous spectra have no distinct lines, just a range of colors.

When light is "slowed down" (dispersed) by a prism to see lines (distinct wavelengths), if it's emission (atoms emitting), it's emission spectra.

Answer:

Emission Spectra
