例句:
- When a ray of light passes from water or glass into air, the refracted ray is bent away from the perpendicular so that the angle of refraction is greater than the angle of incidence. 伯莎M.克拉克. 科学通论.
- The law of reflection always holds, however, no matter what the reflecting surface is,--the angle of reflection always equals the angle of incidence. 伯莎M.克拉克. 科学通论.
- Observation and experiment have taught us that light is always reflected in such a way that the angle of reflection equals the angle of incidence. 伯莎M.克拉克. 科学通论.
- The angle _AOR_ is called the angle of incidence. 伯莎M.克拉克. 科学通论.
- When light passes from air into water or glass, the refracted ray is bent toward the perpendicular, so that the angle of refraction is smaller than the angle of incidence. 伯莎M.克拉克. 科学通论.
