Question

Чому ввечері, увімкнувши в кімнаті світло, ви можете бачити власне зображення у віконному склі, а в день у ясну погоду це неможливо

Answer 1

Why can you see your own reflection in a window when you turn on the light in a room in the evening, but it is not possible to see it during the day in clear weather?

When you turn on the light in a room in the evening, you can see your own reflection in a window because the light inside the room is much brighter than the light outside. This creates a situation where the window acts as a mirror, reflecting your image back to you.

During the day in clear weather, it is not possible to see your own reflection in a window because the outside light is much brighter than the light inside the room. When the outside light is brighter, it overpowers the light inside the room and prevents your reflection from being visible in the window.

To understand this phenomenon, it's important to consider the principles of reflection and the behavior of light. When light strikes a surface, it can be absorbed, transmitted, or reflected. In the case of a window, some of the light from the room is reflected off the surface of the glass. If the light inside the room is brighter than the light outside, the reflection becomes more noticeable, allowing you to see your own image in the window.

During the day, when the sun is shining brightly, the outside light is much stronger than the light inside the room. This means that the reflection off the window is much weaker compared to the ambient light, making it difficult to see your own reflection.

In summary, the ability to see your own reflection in a window when you turn on the light in a room in the evening is due to the contrast between the brightness of the light inside the room and the outside light. During the day in clear weather, the outside light is much brighter, making it difficult to see your reflection in the window.
