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 is the image formed by a plane mirror is called virtual rather than real?
It is called
virtual because the light ray that formed the image didnot actually come from the object, the rays
only appeared to have diverged from the object. It is the apparent ray that
form such images.
