This nugget explains spherical mirror and its types and uses. It talks about concave and convex mirrors, types of images, and image formation by concave and convex mirror.

This video is a lesson on reflection in spherical mirrors, using everyday objects like spoons to explain the concepts. The teacher covers technical terms such as center of curvature, radius of curvature, and focal length, and explains...

This video provides a basic understanding of lenses, explaining how they work to focus light and form images. It covers the different types of lenses, their uses in various devices, and even highlights how our own eyes function as...

In this video the focus is on where and why concave mirrors are used, as well as the image formation and types of images. Students will learn that concave mirrors are used in many ways to magnify objects, create real and virtual images...

This nugget explains what a Polyhedron is. It also explains convex, concave and regular Polyhedrons along with the Euler's formula.

👉 Learn how to determine the concavity of a function. A function is said to be concave up (convex) if the graph of the curve is facing upwards and the function is said to be concave down (concave) if the graph is facing down. To test for...

Have you ever visited a house of mirrors and seen a wacky-looking version of yourself? In this activity you can construct your own miniature house of mirrors. Try it out and see what funny reflections you can make!

Using animation and real world examples, this video explores the change in kinetic energy of particles with heating and cooling that produces expansion and contraction and change in density in matter. Students will observe and come to...
