Question 1

A beam of monochromatic light with an initial intensity I0 I_0\,I0​ passes through a dusty region of space. The dust particles scatter the light such that the amplitude of the electric field of the light wave is reduced by 60%.

What is the intensity of the transmitted light wave in terms of I0I_0I0​?

A

425I0\frac{4}{25} I_0254​I0​

B

925I0\frac{9}{25} I_0259​I0​

C

25I0\frac{2}{5} I_052​I0​

D

35I0\frac{3}{5} I_053​I0​
