Harry is reading an online summary of the law of reflection. the site states that after light hits a mirror, the angle of reflection is the angle between the reflected ray and the normal, which is the surface of the mirror.
which statement corrects an error on the site?
the normal is a line perpendicular to the surface of the mirror.
the normal is a line perpendicular to the incoming ray.
the angle of reflection is the angle between the incoming ray and the normal.
the angle of reflection is the angle between the reflected ray and the incoming ray.

The normal is a line perpendicular to the surface of the mirror.

Explanation:

By definition, the normal to a surface corresponds to a line perpendicular to the surface. Therefore, the normal of a mirror is perpendicular to the surface of the mirror. So, the statement

"the normal, which is the surface of the mirror."

is wrong.

The law of reflection states that the angle of incidence on the surface of a mirror is equal to the angle of reflection, where the two angles are defined as:

- Angle of incidence: the angle between the incoming ray and the normal to the mirror

- Angle of reflection: the angle between the reflected ray and the normal to the mirror

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
