tia tới

tia tới

Tia tới chiếu xiên từ không khí vào mặt nước.

Definition
  1. Noun:
    • Incident ray: In physics and optics, the ray of light that arrives at and strikes a surface before any reflection or refraction occurs.
Usage Examples
  • Noun:
    • Góc giữa tia tới pháp tuyến gọi là góc tới. (The angle between the incident ray and the normal is called the angle of incidence.)
    • Tia tới đập vào bề mặt gương. (The incident ray strikes the mirror's surface.)
Advanced Usage
  • The term is primarily used in scientific and educational contexts to describe the initial path of light in geometric optics.
Variants and Related Words
  • Tia phản xạ (n): reflected ray.

    • Tia phản xạ nằm trong cùng mặt phẳng với tia tới pháp tuyến. (The reflected ray lies in the same plane as the incident ray and the normal.)
  • Tia khúc xạ (n): refracted ray.

    • Khi đi qua mặt phân cách, tia tới bị bẻ cong thành tia khúc xạ. (When passing through the interface, the incident ray is bent to become the refracted ray.)
Synonyms
  • Incident beam: A broader term often used for a collection of incident rays.
Related Scientific Terms
  • Góc tới (n): angle of incidence.
    • Định luật phản xạ nói rằng góc tới bằng góc phản xạ. (The law of reflection states that the angle of incidence equals the angle of reflection.)
