AI Thread Summary
You cannot see your face in newspapers or walls because these surfaces do not reflect light in an orderly manner. Mirrors have highly polished surfaces that direct light back to the viewer, allowing for a clear reflection. In contrast, walls and newspapers have rough textures that scatter light, preventing a coherent image from forming. This scattering effect makes it impossible to see a reflection on these materials. Understanding the physics of light reflection clarifies why certain surfaces reflect images while others do not.

Ques) Why we cannot see our face in the newspaper and in the wall ?

Well, to "see" your face on something, you need light to bounce of the surface in a orderly fashion. Therefore in highly polished surfaces like mirrors the light gets bounced off in one direction. whereas in something like the wall, the surface is very rough although it might seem "smooth" to touch therefore the light gets scattered and no reflection is seen!
 
ok ...Thanx :smile:
 

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
