Why is light scattering by diffused reflection important to us?

Question

physics

Answer 1

Because it enables us to see in the shadow.

If there would be no diffused light every shadow would be completely dark. For example walking under hot sun, you could not see the ground where your shadow is.

Answer 2

Diffuse reflection is important to us because it makes us capabel to see things. without diffused reflection, like in the case of mirrors, you will just see images of the object from which the light comes. For example, the light scatters from the page of a book is diffused reflection, if it were not you would not be able to read from the page, rather you would see image of the object from which the light comes and fall on the page.

Answer 3

And on the moon where there is no atmosphere, a dark cave is pitch black as soon as you enter it - even though you are standing right at the mouth of the cave!
