FAQs
1. How does a visible spectrophotometer work?
It passes visible light through a sample, and a detector measures how much light is absorbed or transmitted at different wavelengths.
2. What types of samples can be analyzed with a visible spectrophotometer?
It is commonly used for analyzing colored solutions, biological samples, chemicals, and industrial materials.
3. What is the function of a cuvette in a spectrophotometer?
A cuvette holds the liquid sample, allowing light to pass through for absorbance or transmittance measurements.
4. Can a visible spectrophotometer measure color intensity?
Yes, it is used to quantify the intensity of color in solutions, which is useful in food, pharmaceuticals, and chemical industries.
5. What is Beer-Lambert’s law in spectrophotometry?
Beer-Lambert’s law states that absorbance is directly proportional to the concentration of the absorbing substance and the path length of light.
