When light shines onto a mirror how are the angle of incidence and angle of reflection related?

Answer 1

The Law of Sines is he relationship between the incidence angle and the reflection angle:

Sin(I)/Incident velocity = Sin(R)/reflection velocity. If the incident and reflection velocity are the same, then the angles are the same.

Answer 2

Angles of Incidence and angles of reflection share the same plane and velocity and have the same size angle opposite the line normal to the point of incidence.

Fermat showed that the law of sines covers the angles of incidence , reflection and refraction.

Answer 3

The refractive index of light in medium one multiplied by (sine angle of refraction) equals the refractive index of light in medium two times (sine angle of incidence)

(Theta is normally used to represent the angle not x.)

where the refractive index is the speed of light in a vacuum divided by the speed of light in the medium.

nrsinxr=nisinxi

they are always equal- apx

Answer 4

-- The angle of incidence is the angle between the perpendicular to the reflecting surface

and the direction from which the light arrives before reflection.

-- The angle of reflection is the angle between the perpendicular to the reflecting surface

and the direction toward which the light departs after reflection.

Answer 5

The angle of incidence and the angle of reflection are related in the sense that the two angles are always the same.

They are always equal.

Answer 6

they state that they are equal.

Answer 7

The two angles are the same

Answer 8

Sin I/VI = Sin Ref/VRef
