The wave is a disturbance moving along the medium from one point to another. By observing the ocean waves, it can be analyzed that the crest is moving from one location to another over the given period. The crest is observed to cover the distance. The speed of the object is referred to as how … Read more

Waves are the disturbance that travels from one location to another location through any medium. We can observe the disturbance that travels from one end to another end. For example, if the first coil of the slinky is given forth and back vibration then we can observe the motion of disturbance. Category of waves We … Read more

Waves on a String We can extend the notion of resonance to wave phenomena. Resonances during a wave medium (such as on a string or within the air, for sound) are standing waves; they’re analogous to the resonant oscillation of a mass and spring. Unlike the mass and spring that has solely one resonant frequency, … Read more

A warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air. These gases, also known as greenhouse gases, water vapors have the largest effect. How it Works? The atmosphere allows most of the visible light from … Read more

Modes of vibration are particularly, though by no means are exclusively related to musical instruments. It is another shape of vibration, and most of the musical instruments have more than one mode of vibration, because without it, they would be fairly limited in their musical range. Compare the sounds of a violin (with 4 to … Read more

Integrating qλ (T) over all wavelengths from zero to infinity, we obtain by means of expressions for determinate integrals the surface density of the total black-body radiation flux qv (T) as„ Where the Stefan−Boltzmann constant o is equal to the second formula as shown in the above picture. Similar expressions can also be gained for … Read more

We often encounter some conditions involving the reflection of waves all around us, for example, in the phenomenon of echo, the sound reflected from a distant object reaches the listener with a little delay. Reflection When a wave is an incident on any surface, a part of the incident wave is reflected and a part … Read more

Beats of waves is a term used in physicals and engineering as the envelope of an oscillating signal is a smooth curve outlining its extreme. The envelope then generalizes the concept of amplitude. There is a phenomenon that occurs when two waves meet while traveling along with the same medium and it is known as … Read more

The body is in the periodic motion if the motion is executing and repeating after the equal time intervals, such as the rocking chair and swing in the motion. The periodic function can be defined as the function returning to the same value at regular intervals. Though the periodic motion sounds similar to the oscillatory … Read more

Free Oscillation Free oscillation is a kind of oscillation in which the body oscillates with natural frequency without the help of any periodic force or external force. No energy being add or taken away for this system. In a free oscillation, the sum of potential energy (PE) and kinetic energy (KE) cannot increase the potential … Read more
