In a college hostal , a clever warden in order to know what the students are doing in the room in his absence during night he switched off the light in the corridor and watched the room through a glass partition from the corridor. Explain why the objects in the room are more clearly visible when he switched off the corridor lights than when there is light in the corridor. |
| Answer» Light from the corridor is reflected by the glass pane separating it from the dark room. This reflected light enters our eye along with the light from inside the dark room. Since reflected light is more than the light from the room and also more intense, we cannot see the things inside the room. When the lights in the corridor are switched off, the light from the room now enters our eyes and the visibility improves. | |
