Fog condensed on a glass window is just a very thin layer of water droplets, so why is it so opaque to light? Normally light passes through a water-glass interface just fine, but why not in the case of condensation?

Foggy windows appear opaque because they are covered in tiny water droplets, which scatter and diffuse light, making it difficult for light to pass through and resulting in the appearance of opaqueness.
Windows become foggy when there is a difference in temperature between the inside and outside of the window. This temperature difference causes water vapor from the air to condense on the surface of the window, creating tiny water droplets that fog up the window.
Fog significantly reduces visibility through a window because the tiny water droplets that make up the fog scatter and diffuse light, making it difficult for our eyes to see through the window clearly.
Foggy windows can be prevented by reducing the temperature difference between the inside and outside of the window. This can be achieved by using double-paned windows, adding weather stripping to the window frame, or using a dehumidifier to reduce moisture in the air.
Foggy windows can be cleared by removing the moisture from the surface of the window. This can be done by using a cloth or squeegee to wipe the window, using a hairdryer on a low heat setting, or simply waiting for the temperature inside and outside of the window to equalize and the fog to evaporate.
