The direction of the magnetic field at any point is tangent to the magnetic field line at that point. The aim of this lecture is…

Prime purpose of this lecture is to present on Magnetic Field Direction. Direction of magnetic field at any point is defined as the direction of motion of…

Magnets have been known for centuries. The Chinese and Greeks knew about the “magical” properties of magnets. The ancient Greeks used a stone substance called “magnetite.”…

Basic purpose of this lecture is to present on Lenses: Application of Refraction. There are two main types of lenses: convex lenses—these curve outwards and are fatter…

General purpose of this lecture is to present on Light Refraction and Lenses. Refraction fact 1: As light goes from one medium to another, the velocity changes! Refraction…

Light is a wave, kind of like a wave in the ocean. These light waves carry energy. This energy can do many interesting things, like help…
