Q4. In a completely dark room, if you hold up a mirror in front of you, will you see a reflection of yourself in the mirror?

Answer: No, we will not be able to see ourselves in the mirror in the darkroom because there are no light rays that will come in our eyes after reflecting on the various objects.

👉 In this case “I” am the object. First, light rays have to strike on my body. Then, light rays go to the mirror and get reflected back in my eyes. By this way, I will be able to see myself in the mirror.

But, in the case of the darkroom, I will not be able to see myself in the mirror. 🤷‍♀️
