Have you ever observed how a train or ambulance’s sound alters as it goes by?  The sound gets louder and higher-pitched as it gets closer, and then it seems softer as it passes you.  The Doppler Effect is a scientific phenomena; it’s not just your ears playing games. Train The Basic Idea The shift in … Read more

Have the “wah-wah” sound produced by two musical instruments that are slightly out of tune ever occurred to we? Beats are the term for the fading effect. The meeting of two sounds with slightly differing frequencies is a cool phenomena. Musical instruments What Are Beats? Interference occurs when two sound waves with almost identical frequencies … Read more

Water, music, light, and even the vibrations we experience when we touch a surface are all made of waves. Reflection is one of waves’ primary characteristics. In a nutshell, reflection occurs when a wave strikes a boundary or surface and returns to the original medium rather from being absorbed or passed through. Music What is … Read more

Water, sound, light, and even invisible fields like radio waves are all examples of waves. In actual life, multiple waves frequently pass through the same area simultaneously. Thus, the question that naturally arises is: Light When two or more waves traverse in the same medium, the displacement of any element of the medium is the … Read more

From the sound of music reaching our ears to the ripples in a pond, waves are present everywhere. Have you ever pondered, though, how quickly these waves travel? Waves What is a Travelling Wave? An energy-transferring disturbance that travels through a medium without moving matter is called a traveling wave. We think tossing a stone … Read more

Waves are a vital component of physics because they enable us to understand how energy travels across great distances without the actual movement of matter. How particles in the medium move as a progressive wave come through is one of the first things. Particles Displacement Relation in a Progressive Wave A progressive wave is one … Read more

We are surrounded by waves. Waves are what allow us to see light, hear sound, and even feel the tides in the ocean or the vibrations in strings. Waves are vital to physics, particularly the two fundamental kind longitudinal and transverse waves. Tides Transverse and Longitudinal Waves What is a Wave? A wave is a … Read more

We see several instances of vibrating or oscillating objects in our lives. For example, a guitar string, a swing, or even a car passing over a rough patch of road. All of these oscillations fall within this category. Guitar string Forced Oscillations and Resonance A system is said to be executing free oscillations if it … Read more

Everybody has seen a vibrating tuning fork or a swinging pendulum. Their motion eventually slows down and ceases if they are left alone. However, why does this occur? This is where damping enters the picture. Swinging pendulum The oscillations in presence of dissipative force where amplitude decrease gradually with the passage of time are called … Read more

A body moving to and fro around a mean position in which its acceleration is directly proportional to its displacement and directed towards the mean position is said to be in simple harmonic motion (SHM), a type of periodic motion. The behaviour of energy during motion is one of the most interesting parts of SHM. … Read more
