What is a wave motion in physics?

wave motion, propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

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.

What is a mechanical wave a level physics?

A mechanical wave is a vibration in matter that transfers energy through a material. Mechanical waves have peaks and troughs, frequencies, and wavelengths. Frequency is the number of waves per second, and wavelength is the distance from one peak to the next.

What are two types of wave motion?

There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.

What are the 4 types of waves?

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

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 characteristics of wave motion?

Solution : (i) During wave motion, the particles of the medium vibrate about their mean position. The particles of the medium do not travel from one place to another.
(ii) Wave motion travels at the same speed in all directions.
(iii) During wave motion, energy is transferred from one point to another.

What are the properties of wave motion?

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

What is wave motion and examples?

Wave Motion is the motion of the waves. A wave is defined as a disturbance caused by the propagation of energy in space or a medium. The ripples in water, the propagation of sound, the rays of light, are all examples of wave motion.

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.

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 a transverse wave a level?

Transverse waves A transverse wave is one where the particles oscillate perpendicular to the direction of the wave travel (and energy transfer)

What are the levels of waves?

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 are the different types of waves define each?

There are two basic kinds of waves: electromagnetic and mechanical. Mechanical waves include water waves, sound waves, and waves on ropes or springs. Mechanical waves travel in a medium (such as air, water, glass, or rock). Electromagnetic waves can travel in a medium or in a vacuum.

What causes a 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 5 characteristics of a 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.

Why wave motion is 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.

What are the 4 properties all waves have?

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. All waves can be thought of as a disturbance that transfers energy.

What is the lowest point of a wave called?

The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.

What is the frequency of a wave?

Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.

What are the 7 properties of waves?

There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below.

Is light a plane wave?

Light is a transverse electromagnetic wave, but natural light is generally unpolarized, all planes of propagation being equally probable. If light is composed of two plane waves of equal amplitude by differing in phase by 90°, then the light is said to be circularly polarized.

How is energy transferred by wave motion?

Energy is transferred in waves through the vibration of particles, but the particles themselves move in a perpendicular fashion to the horizontal movement of the wave. Energy is transformed between potential (stored) and kinetic (movement) energy as the particles go from rest to movement and back to rest.

What is wave motion phase?

What is Phase? An important characteristic of a sound wave is the phase. Phase specifies the location or timing of a point within a wave cycle of a repetitive waveform. Typically, it is the phase difference between sound waves that is relevant, rather than the actual absolute phases of the signals.
