Because a reflection reverses the direction of the component of the wave vector of the light hitting the reflecting surface which is orthogonal to the surface. The component parallel to the surface will not change. This means the light going towards a mirror, will go away from the mirror after reflection. But if it went from the left to the right, it will continue to go from the left to the right. Same with up and down. In three dimensions this is the same as changing the handedness of the image.
A line which is the reflection of the original in y = x.
On a smooth level surface, and with no forces acting on it after the moment of release, it MUST.
It depends on the kind of transformation: it could be reflection or translation.
A reflection.
Light reflections off of a smooth surface are considered to be spectral. Light reflections off of rough surfaces are considered to be diffuse
The reflection of a smooth surface is called a specular reflection, where light is reflected in an organized manner, maintaining the original direction of the light rays.
Specular reflection occurs on a smooth surface, where light rays are reflected in a single direction, like a mirror. This type of reflection follows the law of reflection, where the angle of incidence equals the angle of reflection.
A reflection from a smooth surface is called a specular reflection. This type of reflection occurs when light rays are reflected at the same angle as the incident angle, resulting in a clear and sharp image.
Reflection works best if it is on a smooth shiny surface.
You see a clear reflection of the object's image on the smooth surface.
Specular reflection occurs when light bounces off of a smooth surface such as a mirror!
An uneven surface will give off a diffused reflection, scattering light in multiple directions. This diffuse reflection can reduce glare and create a more uniform lighting environment compared to a smooth, mirror-like surface.
A smooth texture, such as glass or polished metal, reflects light evenly due to its lack of roughness or irregularities on the surface. This smooth surface allows light to bounce off uniformly, creating a consistent reflection.
When light hits a smooth surface, it reflects in a predictable manner called specular reflection. This type of reflection results in a clear and well-defined image being formed. Examples of smooth surfaces that exhibit specular reflection include mirrors and still water surfaces.
Specular reflection reflects off a smooth surface, where light rays bounce off at the same angle they hit the surface. This type of reflection produces clear and sharp images.
When light strikes a smooth surface, it undergoes regular reflection, also known as specular reflection. This means that the angle at which the light hits the surface is equal to the angle at which it is reflected, resulting in a clear and well-defined reflection.
