tia ló
Definition
- Noun:
- Emergent ray: In physics, particularly optics, the ray of light that exits a medium (such as a lens, prism, or block of glass) after undergoing refraction or reflection.
Usage Examples
- Noun:
- Tia ló khúc xạ qua lăng kính. (The emergent ray is refracted through the prism.)
- Góc của tia ló phụ thuộc vào chiết suất của chất liệu. (The angle of the emergent ray depends on the material's refractive index.)
- Hãy vẽ đường đi của tia tới và tia ló. (Draw the path of the incident ray and the emergent ray.)
Advanced Usage
"tia ló khúc xạ": Refracted emergent ray. This specifies the ray has bent due to passing from one medium to another.
- Tia ló khúc xạ lệch xa pháp tuyến. (The refracted emergent ray bends away from the normal.)
"tia ló phản xạ": Reflected emergent ray. This specifies the ray has bounced off a surface.
- Trong gương phẳng, tia ló phản xạ có góc bằng góc tới. (In a plane mirror, the reflected emergent ray has an angle equal to the angle of incidence.)
Variants and Related Words
Tia tới (n): Incident ray. The ray of light that arrives at a surface.
- Tia tới chiếu vuông góc với bề mặt. (The incident ray strikes perpendicular to the surface.)
Pháp tuyến (n): Normal line. An imaginary line perpendicular to a surface at the point of incidence, used to measure angles.
- Góc được đo từ pháp tuyến. (The angle is measured from the normal.)
Synonyms
- Emergent beam: A collection of parallel emergent rays.
- Outgoing ray: A more general term for a ray exiting a system.
Related Scientific Concepts
Định luật khúc xạ ánh sáng (Snell's Law): The law governing the relationship between the angles of the incident and refracted rays.
- Định luật Snell dự đoán hướng của tia ló. (Snell's Law predicts the direction of the emergent ray.)
Lăng kính (Prism): A transparent optical element that separates white light into its component colors, producing multiple emergent rays.
- Lăng kính tạo ra nhiều tia ló có màu sắc khác nhau. (A prism creates multiple emergent rays of different colors.)
