Question

Susan was traveling in an airplane. She looked out of a window in the airplane and saw clouds in the sky.

Why could Susan see clouds through the window of the airplane?

Answer 1

Susan was able to see clouds through the airplane window because the light from the outside passes through the transparent glass, allowing visibility of external objects like clouds. Clear conditions further enhance this visibility.

Step-by-step explanation:

Susan could see clouds through the window of the airplane because light, which travels in straight lines unless obstructed or refracted, allows us to see objects. In the case of the airplane window, the light passes through the glass, enabling passengers inside the plane to observe external elements such as clouds. Visibility through any transparent medium, such as an airplane window, depends on the clarity of that medium and the absence of obstructions or impairments like fog, dust, or smog. On a clear day, the light is not significantly scattered or absorbed, providing a clear view of the sky and clouds outside. However, on days with heavy smog or fog, the light gets scattered and absorbed, limiting visibility much like in big cities where you can't see far on days with heavy smog.
