Those interested in the Application ultrasonic waves category often ask the following questions:

☑️ Are lamb waves ultrasonic waves?

"Ultrasonic" is an adjective referring to sound waves at frequencies greater than the typical limit of human hearing. "Lamb waves" are elastic waves propagating in solid plates. Their particle motion lies in the plane that contains the direction of wave propagation and the plate normal (the direction perpendicular to the plate). The characteristic that defines a "Lamb wave" is completely different from the characteristic that defines an "ultrasonic" wave, so the question is a lot like asking "Are human beings American people ?" Some Lamb waves are ultrasonic, and the rest aren't.

☑️ Does sonar use ultrasonic waves?

  • Ultrasonic waves are used in ships, not only for navigation but also for locating objects underwater . These sound waves travel a lot faster through water than air. Submarines make use of these types of sound waves and use it for a type of navigation called sonar, which is more like underwater radar.

☑️ Will ultrasonic waves show any polarisation?

Ultrasonic waves are high-frequency sound waves… These waves are longitudinal in nature, hence it cannot be polarized. Only transverse waves can be polarised.

☑️ How fast are ultrasonic sound waves?

Ultrasonic sound waves travel at the same speed as lower frequency sound waves. The medium determines the speed at which a sound wave, which is mechanical energy, can travel. Sound waves travel faster in liquids than in a gas (like air), and travel faster still in solids. The speed at which a sound wave travels is generally independent of the frequency of that sound.

☑️ What are ultrasonic and infrasonic waves?

Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)

How are ultrasonic waves made and how are they produced?

  • Unlike normal ways of making sound, which often involve striking a surface, ultrasound is made using electrical equipment that vibrates with an extremely high frequency. Crystals of materials such as quartz vibrate very fast when electricity is passed through them—an effect called “piezoelectricity.”

Velocity of ultrasonic wave using acoustic grating?

The ultrasonic waves generated with the help of a quartz crystal inside the liquid in a container sets up standing wave pattern consisting of nodes and anti-nodes. The nodes are transparent and anti-nodes are opaque to the incident light. In effect the nodes and anti-nodes are acts like grating(a setup of large number of slits of equal distance) similar to that of rulings in diffraction grating. It is called as acoustic grating or aqua grating. Hence, by using the condition for diffraction, we can find the wavelength of ultrasound and thereby the velocity of sound in the liquid medium.

What is shear wave in ultrasonic detection?

  • The shear wave is a wave motion in which the particle motion is perpendicular to the direction of propagation.

Why does ultrasonic sound not work on dogs?

Are light waves electromagnetic waves?

Usually when one says light waves, one is referring to Visible light. Any light wave, and hence visible light, is an electromagnetic wave. As an electromagnetic wave, it is also a transverse wave. The oscillating electric and magnetic fields of an electromagnetic wave in free space are oscillating with a direction perpendicular yo the direction of movement of the wave. The velocity of an electromagnetic wave is the sped of light. This is a sensible things since light is an electromagnetic wave. In a vacuum all electromagnetic waves travel at the same speed. In matter, if the matter allows an electromagnetic wave to propagate, the speed is slower than the speed of light and in optics we say the speed is reduce by the index of refraction, v=c/n. Electromagnetic waves, like all waves, have velocity, wavelength, frequency, amplitude and phase. As with all transverse waves, electromagnetic waves can be polarized, or we say, have a polarization. Electromagnetic waves have electric and magnetic fields that are sinusoidal in space and time. These electromagnetic fields satisfy Maxwell's equations, i.e. the fundamental laws of electromagnetism. There is a quantum version of electromagnetic theory called electrodynamics and that theory is the necessary edification of Maxwell's equations to describe the quantum nature of light. Thus, even when we are discussing light as photons, it is correct to say light is an electromagnetic wave as such is manifested within quantum electrodynamics.
