The Lambert-Beer law is given by the equation $I = I_0 e^{-\mu x}$, where $I_0$ is the incident intensity, $I$ is the transmitted intensity, $\mu$ is the absorption coefficient, and $x$ is the thickness of the absorber sheet.

The purpose is to measure the absorption coefficient to understand how much light is absorbed as it passes through the glass and plastic, which is important for various applications in optics and material science.

The intensity of the transmitted light decreases exponentially with the thickness of the absorber sheet, as described by the equation $I = I_0 e^{-\mu x}$.

<p>The power meter is used to measure the incident intensity ($I_0$) and transmitted intensity ($I$) of the light passing through the absorber sheet, which are essential for determining the absorption coefficient.</p> Signup and view all the answers

<p>The absorption coefficient ($\mu$) is directly related to the decrease in intensity of the transmitted light, as described by the Lambert-Beer law equation $I = I_0 e^{-\mu x}$. A higher absorption coefficient leads to a greater decrease in intensity for a given thickness of the absorber sheet.</p> Signup and view all the answers
