What are opposite rays
👉 Learn essential definitions of points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A...

Understanding Lens Formation Using Radar Diagrams
The video is about using radar diagrams (also known as ray diagrams) to investigate how the type of lens used and the distance between the lens and object affect the formation of an image. The video shows four different ray diagrams,...

What are supplementary angles
👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

Converging lens focussing rays of light, animation.
This is a biconvex lens. The paths of the rays are changed due to refraction, which occurs as the speed of light in glass is lower than the speed in air. The point at which the rays meet is called the focus, and the distance from the...
