What is wave Ncert?

Spread the love

A form of disturbance that travels through a material medium as a result of repeated periodic motion of the medium particles about their mean positions without any transportation of matter is called a wave.

What is wave in physics class 11?

A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.

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 wave period class 11?

Wave Period (T) : The time taken by a particle of the medium to complete one vibration or Wave period is the time during which one complete wave is set up in a medium.

What are 4 types of waves?

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

What are the 6 types of waves?

Usually, waves are around us, they can be sound waves, radio waves, water waves, sine waves, cosine waves, string waves, slinky waves, etc. These are created through disturbance. There are three types of waves.

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 waves and its types?

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 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.

What are the 5 properties of waves?

What are the main properties of waves? The basic properties of a wave are wavelength, frequency, time period, speed and amplitude.

What is the full form of wave?

The full form of WAVE is Wireless Audio Visual Email.

What are the 4 characteristics of waves?

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. The amplitude of a wave can be described as the maximum distance the molecules are displaced from their starting place .

What is velocity of wave?

The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.

What is 1 period of a wave?

Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds, e.g. one wave every 6 seconds.

What is amplitude of a wave?

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

What are the 7 kinds 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 the 7 types of sea waves?

  • Spilling waves. Also known as mushy waves in the beach-goers’ terminology, these waves are formed at gentle inclinations of the ocean floor.
  • Plunging Waves.
  • Surging waves.
  • Collapsing waves.
  • Tidal waves.
  • Tsunamis.

What are the 7 types of energy waves?

The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV) light, X-rays and gamma-rays.

What are the 3 properties of waves?

A wave can be described by its length, height (amplitude) and frequency.

What is the unit for frequency?

The SI unit for frequency is the hertz (Hz).

What causes a wave?

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 2 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.

What type of wave is sound?

A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave. Sound waves are longitudinal waves.

What type of wave is light?

1. Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM – you have light.

Is wavelength high or low?

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
