What is wave motion and its types?

There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.

What is wave motion in physics class 9?

Wave motion is the propagation of disturbances, produced on one part of a medium by the vibration of its particles, to all its other parts.

What is simple wave motion?

Simple wave motion in one dimension means that the particle is constrained to move along a line, instead of moving in other space.

What are the properties of wave motion?

The basic properties of a wave are wavelength, frequency, time period, speed and amplitude.

What causes wave motion?

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

What are the 3 types of wave motion?

Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.

What is wave motion PDF?

Wave Motion 1. 16.1 Wave. A wave is a disturbance which propagates energy and momentum from one place to the other without the transport of matter. (1) Necessary properties of the medium for wave propagation : (i) Elasticity : So that particles can return to their mean position, after having been disturbed.

Who Discovered wave motion?

In the 18th Century, French mathematician and scientist Jean Le Rond d’Alembert derived the wave equation, a thorough and general mathematical description of waves, which laid the foundation for generations of scientists to study and describe wave phenomena.

What are the 4 types of waves?

  • Microwaves.
  • X-ray.
  • Radio waves.
  • Ultraviolet waves.

What is the speed of wave motion?

In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time. In equation form, If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s.

What are the 7 types of waves?

These 7 types of waves are as follows: Radio Waves, Microwaves, Infrared, Visible, Ultraviolet, X-Ray, Gamma Rays. Radio waves have the longest wavelength and small frequency while the gamma rays have shortest wavelength and high frequency.

What are two types of waves?

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

What are 4 wave properties?

No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics: amplitude, wavelength, frequency, and speed.

What are the 5 characteristics of wave?

The five main characteristics of sound waves include wavelength, amplitude, frequency, time period and velocity. Wavelength: The most important characteristic of sound waves may be the wavelength.

What is wave motion class 11?

Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.

What are some examples of waves?

Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through.

How do waves carry energy?

‘Wave’ is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.

What is frequency of a wave?

Frequency is defined as the number of oscillations of a wave per unit time being, measured in hertz(Hz). The frequency is directly proportional to the pitch. Humans can hear sounds with frequencies ranging between 20 – 20000 Hz.

What are the main parts of a wave?

Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest. Wave Length: The distance between two consecutive wave crests or between two consecutive wave troughs.

What type of wave is light?

Light waves are just one type of electromagnetic wave. Other electromagnetic waves include the microwaves in your oven, radio waves, and X-rays. Light waves are regarded as a varying electric field (E) coupled with a varying magnetic field (B), at right angles to each other and to the direction of travel.

Why wave motion is doubly periodic?

A wave particle repeats its motion after fixed interval at every location, and becomes periodic in time. The form of wave also repeats itself after equal distances, and becomes periodic in space. Thus, wave motion is doubly periodic. i.e. periodic in space and time.

Which is not the characteristics of a wave motion?

Solution : (f) Rectilinear propagation is not a wave characteristic because a wave does not necessarily travel in a straight line path.

What is transverse wave motion?

transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.

What is the study of waves called?

A seismologist is a scientist who studies earthquakes and seismic waves.

Is water a wave?

Water waves are a combination of longitudinal and transverse waves and are surface waves. The distortions propagate with the wave speed, while the water molecules remain at the same positions. Most of the ocean waves are produced by wind, and the waves towards the coast pass the energy from the wind offshore.
