angle of reflection
Noun: - The angle between a reflected ray and a line perpendicular to the reflecting surface at the point of incidence: In physics, this is the angle formed by a ray of light or other wave after it bounces off a surface and a line drawn at a 90-degree angle (the normal) to that surface at the exact point where the reflection occurs.
The term "angle of reflection" is used primarily in the context of optics and wave physics to describe the direction of a reflected wave relative to the surface. - It is a specific, measurable quantity. - It is always discussed in relation to the angle of incidence (the angle between the incoming ray and the normal). - According to the law of reflection, the angle of reflection is equal to the angle of incidence.
- Noun:
- When teaching optics, the professor emphasized that the angle of reflection is always equal to the angle of incidence.
- To design the periscope, the engineers carefully calculated the angle of reflection for each mirror.
- "Law of Reflection": The fundamental principle stating that the angle of incidence is equal to the angle of reflection, and that the incident ray, reflected ray, and normal all lie in the same plane.
- The simple operation of a mirror is governed by the law of reflection.
- Angle of incidence (n): The angle between an incoming ray and the normal to the surface.
- The angle of incidence determines how much light is reflected and how much is refracted.
- Normal (n): In this context, an imaginary line drawn perpendicular to a surface at the point where a ray hits it.
- All angles are measured from the normal, not from the surface itself.
- Reflectance (n): The measure of the proportion of light or other radiation reflected by a surface.
- A polished metal has a high reflectance.
- Reflection angle: A less common but direct synonym for angle of reflection.
(While "angle of reflection" itself is not typically part of a phrasal verb, it is central to related verbal phrases.) - To obey the law of reflection: To behave according to the principle that the angle of reflection equals the angle of incidence. - All specular (mirror-like) reflections obey the law of reflection.
