Centripetal Force Sources
The centripetal force required for circular motion can arise from various sources, including tension in a string (as in the case of a swinging pendulum), gravitational attraction (as in the case of planets orbiting the Sun), friction (as in the case of a car turning), or the normal force (as in the case of a…

Centripetal Acceleration
The centripetal force causes the object to accelerate towards the center of the circle. This acceleration is known as centripetal acceleration and is always directed perpendicular to the velocity of the object, towards the center of the circle.

Centripetal Force
In circular motion, an object experiences a force directed towards the center of the circle called the centripetal force. This force is required to keep the object moving in a circular path and is responsible for changing the object’s direction without changing its speed.

Concept of Circular Motion
Circular motion describes the movement of an object along the circumference of a circle. This motion can be uniform, where the speed remains constant, or non-uniform, where the speed varies.

Wave Optics and Modern Physics
Wave optics, also known as physical optics, considers light as a wave phenomenon and is used to explain optical phenomena such as interference, diffraction, and polarization. It plays a crucial role in modern physics, providing insights into the behavior of light at the quantum level and facilitating the development of advanced technologies in fields such…

Geometric Optics
Geometric optics is a branch of optics that describes light propagation in terms of rays and is applicable when the size of objects and apertures involved is much larger than the wavelength of light. It provides a simplified framework for understanding phenomena such as reflection, refraction, and image formation.

Optical Instruments and Systems
Optical instruments and systems utilize the principles of optics to manipulate light for various purposes. Examples include lenses, mirrors, prisms, and optical fibers. These instruments are used in imaging systems (such as microscopes and telescopes), communication systems (like fiber optics), and various other technologies.
