A tide is a disturbance in a medium that carries energy without a net movement of particles. It might take the kind of elastic deformation, a sport of pressure, electrical or magnetic intensity, electrical potential, or temperature.

Introduction the Waves

Transfers energy.Usually involves a periodic, repetitive Movement.Does not an outcome in a net movement of the medium or particles in the medium (mechanical wave).


Electromagnetic Waves:

Radio signals, light rays, x-rays, and also cosmic rays.

Mechanical waves:

A tide which demands a tool in order to propagate itself. Sound waves, waves in a Slinky, and also water waves space all examples of this.

Matter Waves:

Any relocating object can be described as a wave once a rock is dropped into a pond, the water is disturbed native its equilibrium positions together the tide passes; it return to the equilibrium position after the wave has passed.

Electromagnetic Waves:

These waves room the disturbance the does not need any object medium for propagation and also can quickly travel with the vacuum. Castle are produced due to various magnetic and electric fields. The periodic changes that take ar in magnetic electrical fields and also therefore known as Electromagnetic Wave

Electromagnetic wave

Wave speed Formula

It is the total distance covered by the wave in a given time period. The formula because that wave speed is offered as,

Wave speed = distance Covered/Time taken

Properties the Waves

The prime properties the waves room as follows:

Amplitude – Wave is an energy transport phenomenon. Amplitude is the height of the wave, usually measured in meters. It is straight related come the amount of energy lugged by a wave.

Wavelength – The distance between identical points in the nearby cycles the crests of a tide is called a wavelength. That is also measured in meters.

Period – The duration of a wave is the moment for a fragment on a medium to do one finish vibrational cycle. Together the period is time, therefore is measure up in units of time together as seconds or minutes.

Frequency – Frequency that a tide is the number of waves happen a point in a particular time. The unit the frequency is hertz (Hz) i beg your pardon is same to one tide per second.

The duration is the mutual of the frequency and vice versa.

\(Period = \frac1Frequency\)


\(Frequency= \frac1Period\)

Speed – The rate of an object way how fast an object moves and is normally expressed together the distance took trip per time the travel. The speed of a wave refers to the distance travelled by a given allude on the wave (crest) in a provided interval that time. The is –

\(Speed= \fracDistanceTime\)

Speed of a wave is for this reason measured in meter/second i.e. M/s.
