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?
When drawing a ray diagram of a flat mirror why are the reflected rays traced back to a point behind the mirror
Plane mirror images
are always virtual images, the ray of light virtually converge behind the mirror
and the image is formed behind the mirror, thereforeto form atrace of light ray for the plane mirror , we have to extend behind the
mirror.
