what does a spectrometer physically measure? *\nabsorbance of light at a specific wavelength\nabsorbance of light at all wavelengths\nreflection of light at a specific wavelengths\nreflection of light at all wavelengths
Answer
Brief Explanations:
A spectrometer measures the absorption of light across different wavelengths. It separates light into its component wavelengths and can determine how much of the light is absorbed at each wavelength. It is not primarily about reflection, and not just at a single specific wavelength but across a range.
Answer:
Absorbance of light at all wavelengths
