Question:
A sample has an absorbance of 2. Its transmittance would be:
A sample has an absorbance of 2. Its transmittance would be:
Show Hint
The higher the absorbance of a sample, the lower its transmittance, as more light is absorbed by the sample.

- 1.1
- 0.8
- 0.1
- 0.01
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Transmittance (\( T \)) and absorbance (\( A \)) are related by the formula:
\( A = -\log_{10}(T) \)
Given \( A = 2 \):
\( T = 10^{-A} = 10^{-2} = 0.01 \)
Therefore, the transmittance of the sample is 0.01 or 1%.
