Science > Physics > Gravitation >Newton’s Law of Gravitation In this article, we shall study Newton’s law of gravitation, its universality, and universal gravitation constant. Newton’s Law of Gravitation: Statement: Every particle of matter in the universe attracts every other particle of matter with a force which is directly proportional to the product of their […]
Science > Physics > Refraction of Light > Total Internal Reflection of Light In this article, we shall study the phenomenon of total internal reflection and its applications. Total Internal Reflection of Light and its Explanation: Let us consider a point source O in a denser medium (Water). Let XY be the boundary separating the […]
Science > Physics > Refraction of Light > Introduction to Refraction of Light Refraction of Light: When light ray travelling in one optically active medium enters another optically active medium, then the light ray deviates from its path. This phenomenon is known as the refraction of light. Laws of Refraction: The ratio of the sine of […]
