30 degrees as the angle of reflection is equal to the angle of incidence
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.
Also 23 degrees.
The answer depends on knowing what the plane mirror hhas a 20-degree angle relative to!
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
angle of incidence is equal to angle of reflection.
reflection.
The angle of incidence is equal to the angle of reflection in a plane mirror. This is known as the law of reflection, which states that the angle at which a light ray hits a mirror is equal to the angle at which it bounces off the mirror.
No, if the mirror is flat (a plane), the angle of incidence always equals the angle of reflection.
30 degrees as the angle of reflection is equal to the angle of incidence
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 perpendicular to a plane mirror is a line that is at a 90-degree angle to the mirror's surface. It is important for understanding the reflection of light rays off the mirror's surface, as the angle of incidence is equal to the angle of reflection with respect to this perpendicular line.
put a real answer on here, not Study and youll "Know" not now
The angle of incidence and the angle of reflection are equal by the law of reflection when a ray of light reflects off a plane mirror.
Also 23 degrees.
For normal incidence of light on a plane mirror surface, the angle of incidence is 0 degrees and the angle of reflection is also 0 degrees. This means that the light ray hits the mirror surface perpendicularly and reflects back along the same path.
When light strikes a plane mirror, it is reflected in accordance with the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This reflection results in the formation of a virtual image that appears to be the same distance behind the mirror as the object is in front of it.
