​What will be the percentage transmission when absorbance is 1, 2, and 3 respectively?​

Correct option is A

Explanation-

The relationship between absorbance (A) and percentage transmission (%T) is given by:

$$A = -\log_{10}(T) \quad \text{or} \quad T = 10^{-A}$$

Then, percentage transmission is:

                                                               $$\%T = T \times 100 = 10^{-A} \times 100$$

Now calculate for each:
                            A = 1:
                                                       $$\%T = 10^{-1} \times 100 = 0.1 \times 100 = 10\%$$

                           A= 2 :

                                                        $$\%T = 10^{-2} \times 100 = 0.01 \times 100 = 1\%$$

                           A= 3 :

                                                      $$\%T = 10^{-3} \times 100 = 0.001 \times 100 = 0.1\%$$

So, the correct answer is Option A -10, 1, 0.1​​
