What are the Different Types of Sound Sound can be of different types—soft, loud, pleasant, unpleasant, musical, audible (can be heard), inaudible (cannot be heard), etc. Some sounds may fall into more than one category. For instance, the sound produced when an aeroplane takes off is both loud and unpleasant. The sound produced by a marble cutter, on the other hand, may not be … [Read more...] about What are the Different Types of Sound

What is Motion and Types of Motion
What is Motion When a body does not change its position with time, we can say that the body is at rest, while if a body changes its position with time, it is said to be in motion.Analysing Linear MotionLinear motion is motion in a straight line. Non-linear motion is motion that is not in a straight line. When analysing linear and non-linear motion, … [Read more...] about What is Motion and Types of Motion
Lens Formula & Magnification – Lens Power
Numerical Methods In Lens (A) Lens Formula Definition: The equation relating the object distance (u), the image distance (v) and the focal length (f) of the lens is called the lens formula. Assumptions made:The lens is thin. The lens has a small aperture. The object lies close to principal axis. The incident rays make small angles with the lens surface … [Read more...] about Lens Formula & Magnification – Lens Power

What Is The Difference Between Distance And Displacement
What Is Distance And Displacement In Physics The path length between the initial and final positions of the particle gives the distance covered by the particle.Distance is defined as the total length of the path travelled from one location to another. The distance travelled by the car is given by the following, Distance travelled = (200 + 500 + 600 + 300) … [Read more...] about What Is The Difference Between Distance And Displacement
