FAQs on Law of reflection from Fermat's principle Video Lecture - Basic Physics for IIT JAM

1. What is Fermat's principle?
Ans. Fermat's principle states that light follows the path of least time when traveling between two points. This principle explains the behavior of light in terms of minimizing the time taken for light to travel from one point to another.
2. How does Fermat's principle relate to the law of reflection?
Ans. Fermat's principle provides a mathematical explanation for the law of reflection. According to Fermat's principle, light takes the path that minimizes the time taken between two points. In the case of reflection, light follows the path that has the shortest time, which is given by the law of reflection.
3. What is the law of reflection?
Ans. The law of reflection states that the angle of incidence is equal to the angle of reflection. When light hits a surface and reflects, the angle at which it strikes the surface (angle of incidence) is equal to the angle at which it bounces off (angle of reflection).
4. How does the law of reflection apply to mirrors?
Ans. The law of reflection applies to mirrors by determining the angle at which light rays strike the mirror and bounce off. The angle of incidence is equal to the angle of reflection, which allows us to predict the direction in which the reflected light will travel.
5. Can Fermat's principle and the law of reflection be applied to other types of surfaces?
Ans. Yes, Fermat's principle and the law of reflection can be applied to other types of surfaces, not just mirrors. Any smooth surface that reflects light follows the law of reflection, where the angle of incidence equals the angle of reflection. This principle applies to various reflective materials, such as glass, water, and metal.
