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 in physics PDF?
WAVES, , CHAPTER-15, , WAVES, , Wave: A Wave is a sort of disturbance which transmits energy and momentum in a medium, without transfer of particle., Ex: Sound waves, light waves, waves of water, matter waves etc., Wave motion: The propagation of disturbance from one point to another point is called wave, motion., …
What are stationary waves a level physics?
Stationary waves, or standing waves, are produced by the superposition of two waves of the same frequency and amplitude travelling in opposite directions. This is usually achieved by a travelling wave and its reflection.
What is a progressive wave OCR?
progressive wave – a transfer of energy as a result of oscillations. stationary wave – a wave which stores energy in pockets. longitudinal wave – displacement of particles is parallel to direction of energy transfer. transverse wave – displacement of particles is perpendicular to direction of energy transfer.
What is W in wave?
The wavenumber, k, tells us how quickly the wave oscillates in space, while is the frequency, w, tells us how quickly the wave oscillates in time.
What are the classification 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 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 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 is the Doppler effect PDF?
The Doppler effect or Doppler shift is the change in the frequency of the wave whenever there is a relative motion between the source and the wave. A common example of Doppler effect is the change of pitch heard when a vehicle sounding horn approach towards the observer or recedes from the observer.
Is transverse wave a progressive wave?
Furthermore, a progressive wave is of two types; namely, transverse wave and longitudinal wave.
What is a standing wave a level?
Standing waves are formed by the superposition of two travelling waves of the same frequency (with the same polarisation and the same amplitude) travelling in opposite directions. This is usually achieved by using a travelling wave and its reflection, which will ensure that the frequency is exactly the same.
Is sound a progressive wave?
Progressive Waves – Key takeaways A progressive wave is a wave that moves from one position to another. Progressive waves have properties such as wavelength, height, amplitude, velocity, frequency, and period. Examples of progressive waves are sound waves, seismic waves, and ocean waves.
Is progressive wave same as longitudinal wave?
A longitudinal wave is another type of progressive wave. When the displacement of particles of the medium is parallel to the direction of propagation of the wave, the wave is said to be a longitudinal progressive wave.
Are progressive waves longitudinal or transverse?
Progressive Waves A progressive wave oscillates the particles of the medium it is travelling through. A transverse waves has oscillations that are perpendicular to the direction of energy transfer whereas longitudinal oscillate parallel. As mentioned above, phase can be measured by time, degrees or radians.
What is the equation of progressive wave?
Equation of progressive wave is given by y=asinπ(2t−4x),where t is in seconds and x is in meter.
What is 2pi lambda?
The quantity 2π/λ, which occurs in the mathematical description of wave motion, is called the wave number k.
What is value of k in wave?
The wavenumber (k) is simply the reciprocal of the wavelength, given by the expression. k = 1 / λ The wavenumber (k) is therefore the number of waves or cycles per unit distance. Since the wavelength is measured in units of distance, the units for wavenumber are (1/distance), such as 1/m, 1/cm or 1/mm.
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 the 4 basic properties of waves?
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 are 4 types of waves?
- Radio waves.
- Ultraviolet waves.
What are the 8 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 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 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 is velocity of a wave?
Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. 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 the speed of a wave?
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.
