Final answer:
The four characteristics used to interpret the spectrum scientifically are wavelength, intensity, absorbance, and peaks.
Step-by-step explanation:
Four characteristics that are used to help interpret the spectrum are color, taste, odor, and solubility.
However, when it comes to interpreting the spectrum in a scientific context, the four characteristics that are used are wavelength, intensity, absorbance, and peaks.
For example, when analyzing the light emitted from a hot, thin gas, each chemical element or compound produces its own unique spectral pattern. The wavelength, intensity, absorbance, and peaks of the spectral lines can provide valuable information about the gas being studied.
