Classify each statement as True or False. Diffuse reflection does not follow the law of reflection. Only rays of light that enter the eye are seen by the eye. The angle of incidence is equal to the angle of reflection. The image distance for a plane mirror has the same magnitude as the object distance. The image formed by a plane mirror is real and forms in front of the mirror. The ray model for light is valid as long as the objects the light interacts with are smaller than 0.5 micrometers. True False

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
