Chromatic aberration, also referred to as chromatic distortion, color fringing, and spherochromatism, is a common optical phenomenon that occurs when a lens cannot bring all wavelengths of light to a single converging point. Learn more ....

When an object moves in a perpendicular direction with respect to a plane mirror, either towards or away from the mirror with a speed u, the image also moves with the same speed u.

The heat current is the rate at which heat is transferred over time. Because it is a rate of heat energy over time, the SI unit of heat current is joule per second, or watt (W).

Heat flows through material objects through the conduction, with heated particles imparting their energy to neighboring particles.

The angle of repose:- It is the minimum angle that an inclined plane makes with the horizontal when a body placed on it just begins to slide down.

let any inclined plane inclined with θ angle with horizontal and a body which mass is m just begins to slide down.
then,
mg.sinθ =μN
where μ is the coefficient of friction and N is the normal reaction.

N =mg.cosθ
now,
mg.sinθ = μmg.cosθ
tanθ = μ
θ = tan–¹(μ)
here θ is known as angle of repose.

Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body the next time a person exhales. Gas exchange allows the body to replenish the oxygen and eliminate the carbon dioxide. Doing both is necessary for survival.Learn more https://youtu.be/7VGdsQjN-1I?si=uUnuWwwSRw7xQuUz

Newon's First Low of MotionNewton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Newton’s Third Law of Motion is one of the most fundamental principles in physics. This law forms the basis of many interactions in our daily lives, from walking to the functioning of rockets. Newton’s Third Law represents a specific symmetry in the nature of forces and explains how they always exist in pairs, and one body cannot exert a force on another without also experiencing a force.
