Atmospheric Refraction: Definition, Causes, and Effects
What is Atmospheric Refraction? Atmospheric refraction refers to the bending of light as it travels through the Earth’s atmosphere. This occurs because the atmosphere consists of layers with varying optical densities due to differences in temperature and pressure. Light bends toward the normal when moving from a rarer to a denser layer. As light travels…

How to Teach the Concept of a Coupled Pendulum?
What is a pendulum? A pendulum is a fascinating device that consists of a ball-shaped mass, known as the “bob,” suspended by a theoretically massless string from a fixed point. An extension of this is the coupled pendulum, which we shall study in a while. When you displace this bob from its starting position, it…
