light is not matter , it is energy . it does not have any physical state

According to me: everything has a particular shape and properties. And it would be not reasonable to consider light as non-matter Someday we may find that light is a matter but in the present scenario we don't have the reason. { as we know that light is emitted when an electron move from one shell to another and we termed it as energy particles called photons. Today, we used to consider photons as energy particles only which don't have mass. But if we consider that everything is made up of something; then photon will be having a mass. And this can will be proved someday. }

Everything has a particular shape. It's because of the various factors that are continuously affecting it. for e.g.; a growing plant generally needs sunlight,air, and water for survival. thus in order to gain sunlight it grow upwards while to gain water it penetrates deep into the soil. In the same way apples are spherical; as it's easier for the embryo to form a circle(growing in all direction) rather than growing in systematical way(like the edge turns of triangles and squares).

An apple is shaped spherical as per to survive in the nature through its physical properties due to its shape .
