Answer: T = 40%
Explanation: The definition of Transmittance is a part of the incident light that passes through a surface or material moves through the other side of the surface. It is represented as T and is defined as the ratio of the intensity of incident light to the intensity of light that passes through the surface:
[tex]T=\frac{I}{I_{0}}[/tex]
where
I is intensity that passes through
I₀ is incident intensity
When you shine a light on a material and 50% of it is reflected, the remaining 50% will try to pass through. However, 10% is absorbed leaving 40% of the light to move through the other side of the surface.
So, Transmittance of this surface is 40%.
