What is Wave Motion?

Hi friends! My name is Muhammad Jahanzaib and you are reading Zaib Notes. So guys this article is about wave Motion which I can tell you What is wave Motion? How Waves can be Categorized? What is Reflection, Refraction, and Direction of Wave with Full Details?  Thank you for Reading Zaib Notes Article.

WAVE MOTION: -

               A wave is a disturbance that moves outward from its point to origin transfer energy means of vibration with little or no transport of medium.

TYPES OF WAVES: -

                     There are Four Types of waves.

a) Mechanical Waves             b) Electromagnetic Waves     c) Transverse Waves              d) Longitudinal Waves

MECHANICAL WAVES: -

               Those waves which produced by the oscillation of material particles are called Mechanical Waves.

EXAMPLE: -

               Water Waves, Jaunt Waves, Seismic Waves, etc.

ELECTROMAGNETIC WAVES: -

               The waves that propagate by the oscillation of electric and magnetic fields are called electromagnetic waves. They do not require a material medium for the propagation.

EXAMPLE: -

               Visible and Ultraviolet Light, Radio Waves, Micro Waves, X-rays, etc.

TRANSVERSE WAVES: -

               A transverse wave is one in which distribution occurs perpendicular to the direction of motion of the waves. The waves produced by moving one end of a stretched string up and down are transverse because different strings vibrate perpendicular to the direction of propagation of waves. These waves consist of rest and through. The particles' wave moves upward are called rest and the particle that moves downward are called through.

EXAMPLE: -

Radio Waves, Light Waves, etc.

LONGITUDINAL WAVES: -

               A Longitudinal wave is one in which a disturbance occurs parallel to the line of travel of the waves. These waves consist of compression and refraction. This type of wave changes its position.

EXAMPLE: -

               A Sound Wave.

REFLECTION OF WAVES: -

               Waves are reflected when they hit a rigid barrier. The reflected wave makes the same angle to the barrier as incoming waves and travels at the same speed.

REFRACTION OF WAVES: -

               When waves travel from one medium to another their speed change is called refraction.

DIFFRACTION OF WAVES: -

 When waves pass through an opening its speed out due to diffraction.

Question & Answer

 In refraction speed and wavelength both are changed the speed of the wave depends upon the properties of a medium through it travels. The speed of a wave is not the same in deep and shallow water. Waves travel fast in deep water. In this manner assuming water waves are passing from profound water into shallow water, they delayed down. So, when waves are transmitted from deep water into shallow water speed and wavelength decrease.

Question: - What is the effect on diffraction if the opening is made small?

Answer: - Diffraction is the slight bending of a wave as it passed at the edge of an obstacle. If the opening is much larger than the wavelength then very little bending occurs, which is un-noticeable. However, if the two obstacles are comparable, then a considerable bending occurs and be seen easily with the naked eye. Thus, if the wave bends more and more if the opening is made small.
