Why isn’t a shadow as sharp as one can see the object?
In: Physics
Its because of a phenomenon called tyndall effect it basically means scattering of light . When light hits the particles on its path it scatters , when the the object that casts the shadow is closer to the wall then the scattering is lower and a sharper image is obtained.
It is the same reason why there is no sunlight in the vaccum of space as there are no particles for light to bounce off.
