Most Frequently Asked Questions
1. How does a visible spectrophotometer work?
Ans. 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?
Ans. 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?
Ans. A cuvette holds the liquid sample, allowing light to pass through for absorbance or transmittance measurements.
4. Can a visible spectrophotometer measure color intensity?
Ans. 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?
Ans. Beer-Lambert’s law states that absorbance is directly proportional to the concentration of the absorbing substance and the path length of light.
