What is the smallest possible angle of incidence for a light ray travelling toward a mirror?

The smallest possible angle of incidence for a light ray traveling toward a mirror is 1800. This is because then, the light ray will be either parallel or on the principal axis and hence, the angle of incidence would be 00. ...

90 degrees is the largest possible angle of incidence because it is then parallel to the face of the mirror and is grazing the mirror. ...

The point of incidence is the point where the ray of incidence strikes the mirror. ...

surface which reflects angles of incidence.

They are reflected at the angle of incidence.

The angle between the ray and the perpendicular to the mirror (NOT the mirror itself), at the point where the ray hits the mirror is called the angle of incidence. ...

If a light ray is reflected from a flat mirror with a reflection angle of 55o then the angle of incidence was also 55o. When reflecting from a mirrored surface, the angle of incidence equals the angle of reflection. ...

At the point of reflection, those two angles are always equal.

The light ray arrives perpendicular to the plane of the mirror.

The angle of incidence is defined as the angle between the incoming light and the line that is normal to the surface at the point where the light 'hits' the surface. The reflectrion angle is the same as the incidence angle. If the angle between the incident ray and the mirror ray is 50, then the angle of incidence is half of this. That is, 25 degrees. ...

VIERRA! The angle of incidence.

angle of incidence is equal to angle of reflection.

Yes, the angle of incidence always equals the angle of reflection when a straight ray of light hits a mirror that isn't bent. ...

Both are zero. Thereby it obeys the second law of reflection ie angle of incidence is equal to angle of reflection. ...

If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees. ...

The answer depends on knowing what the plane mirror hhas a 20-degree angle relative to! ...

Incident ray or ray of incidence.

image distance is the distance from the point of incidence on the mirror, the where the image is reflected to. object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image. ...

It is the angle at which the incoming light beam strikes the mirror. 'Normal' means 'perpendicular', and the 'angle of incidence' is defined as the angle with respect to the normal. These two facts can serve as powerful clues. ...

put a real answer on here, not Study and youll "Know" not now

It refracts the other way at an angle of 180-i° ("i" being the angle of incidence of the light ray to the mirror). ...

It makes the same angle, on the other side of the normal, at the point of incidence. ...

A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects. ...

Those angles are equal at the point where a ray of light hits the mirror, regardless of the shape of the mirror. ...

The angle of the reflected ray with the normal line to the surface of the mirror is the same as the angle of incidence. Snell's law. ...
