Definition (光)
- specialized
The angle formed between a reflected beam of light or other energy and a line perpendicular to the surface from which it is reflected.
反射角
This phenomenon is only visible at specific angles of reflection.
這種現象只能在特定的反射角度下觀察到。
The angle of incidence is always equal to the angle of reflection, according to the law of reflection.
根據反射定律，入射角總是等於反射角。
In this physics equation, 'R' represents the angle of reflection.
在這個物理方程式中，'R'代表反射角。
