What is meant by Atmospheric Refraction? We can observe the apparent random wavering or flickering of objects seen through a turbulent stream of hot air rising above a fire or a radiator. The air just above the fire becomes hotter than the air further up. The hotter air is lighter (less dense) than the cooler air […]
Magnetic Field Due to a Current Carrying Straight Conductor The Magnetic Field Due to a Current in a Straight Wire: The magnetic field lines are concentric circles as shown in Figure. The spacing between the circles increases as you move away from the wire. This shows that the strength of the magnetic field decreases as […]

What is the Law of Reflection of Light? First law : The incident ray, the reflected ray and the normal at the point of incidence, all lie in the same plane. Second law : The angle of reflection (∠r) is always equal to the angle of incidence (∠i). i.e., ∠r = ∠i […]
How do you figure out Rotational Symmetry? Rotational Symmetry If a shape can fit exactly into itself after a certain rotation (not a full one) about a fixed point (called centre of rotation) then it is said to have rotational symmetry. The angle of turning during rotation is called the angle of rotation. For example, […]
