Amplitude of a Wave The amplitude of a sound wave is the measure of the maximum displacement of particles in a medium from their rest position. In simpler terms, it is the height of a sound wave measured from the middle to the top of a crest or from the middle to the bottom of …
Before learning about average speed and average velocity, we must know the difference between distance and displacement. Distance is a scalar quantity which generally implies how much ground has been covered by the object. On the other hand, displacement is a vector quantity, and it is the shortest possible distance between the start and end …

One might have observed that giving a terminally ill bus a push can cause it to start abruptly. This is due to the lift that provides an upward force when initiated. The change in velocity at this point leads to acceleration, resulting in the bus’s frame accelerating. Acceleration is the measure of the rate at …
Electricity, or electric current, is the flow of electric charge through a conductor. Electric charge is a fundamental property of matter, and it can be either positive or negative. When there is a difference in electric charge between two points, an electric field is created, which can cause electric charge to flow from one point …
The optic nerve, known as the second cranial nerve, plays a vital role in transmitting visual information from the retina to the brain. It is a bundle of nerve fibers responsible for relaying the images we see to the visual cortex, where they are processed and interpreted. Positioned at the back of the eye, the …
The Poles of a magnet are the two opposite points on the magnet where the magnetic field is the strongest. They are called the North Pole and the South Pole, after the Earth’s magnetic poles. The North pole of a magnet is attracted to the South pole of another magnet, while the North pole of …
A telescope is an optical instrument that is used to observe distant objects in space, such as stars, galaxies, planets, and moons. It works by collecting and focusing light from these objects, making them appear larger and brighter than they would to the naked eye. There are two main types of telescopes: refracting telescopes and …
