what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
why does a tree in the path of sunlight create a shadow instead of light spreading around the tree
The tree creates the
shadow because itis an opaque object,
it block the light and with no light is darkness. It can only diffract the
light if it a sharp object
