Hi!
I have two questions:
1) I'm a little confused about image formation. Suppose there's an illuminated object place in front of a mirror. The object has a rough surface causing a diffuse reflection so when lights hits the object, the rays will be scattered all around the room. Now the difficulty that I'm having in understanding is that; Even though the mirror will cause a specular reflection, how is the mirror able to form a complete image of the object if the light incident on it is so scattered? Wouldn't the information of the image carried by that light have to be uniformly incident on the mirror for there to be an exact reflection of the real object?
2) If a laser light is shined on a wall, the dot it makes on the wall can be viewed from every possible direction in the room. For such a narrow beam of light, it seems weird that it would reflect in so many different angles, rather than just one?
Thank you! :)
