If the light ray is straight, and if the mirror isn't bent, then the angle of reflection is exactly 48 degrees, the same number of degrees as the angle of incidence. That's the law 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.
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as the angle of incidence.
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.
30 degrees as the angle of reflection is equal to the angle of incidence
The angle of reflection.
The angle of incidence, which is the angle between the incoming light ray and the normal (perpendicular) to the mirror, is always equal to the angle of reflection, which is the angle between the reflected light ray and the normal. This relationship is described by the law of reflection.
When light with normal incidence strikes a mirror, it reflects back at the same angle in the opposite direction. This is known as specular reflection, where the angle of incidence is equal to the angle of reflection.
The angle of reflection will be equal to the angle of incidence, which is 20 degrees in this case.
When a light ray is directed at a mirror, it reflects off the mirror's surface. The angle of incidence (the angle between the incoming light ray and the normal to the mirror's surface) will be equal to the angle of reflection (the angle between the reflected light ray and the normal). This follows the law of reflection.
The angle of incidence (incoming ray) is equal to the angle of reflection (outgoing ray) at the surface of the mirror. This reflection obeys the law of reflection, where the angle of incidence is measured from the normal (perpendicular line) to the mirror surface.
When a ray of light is directed at a mirror, it will reflect off the mirror's surface at an equal angle but in the opposite direction. This is known as the law of reflection. The angle of incidence, which is the angle between the incident ray and the normal to the mirror's surface, will be equal to the angle of reflection, which is the angle between the reflected ray and the normal.
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.
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.
The angle of reflection is the angle between the reflected ray and the normal to the mirror surface. According to the law of reflection, this angle is equal to the angle of incidence, which is the angle between the incident ray and the normal.
The angle of incidence is 0 degrees for normal incidence, meaning the light ray hits the mirror perpendicularly. The angle of reflection is also 0 degrees, as the reflected ray will be in the same direction as the incident ray.
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as the angle of incidence.
