Question

Richa wants to checks the transmittance of a solution. Which of the following methods can be suggested to get the desired output?

• A. Centrifugation
• B. Spectrophotometry
• C. Chromatography
• D. None of the above

Answer 1

Answer: (B)

Spectrophotometry

A spectrophotometer is a photometer that measures the intensity of light as a function of its wavelength. The ratio of the intensity of the transmitted light to the intensity of the incident light is called transmittance. This transmittance is detected by spectrophotometry. The instrument operates by passing a beam of light through a sample and measuring the intensity of light reaching a detector.

So, the correct answer is option B.
