1, Beam characteristics
Due to the short wavelength of the ultrasonic wave, the ultrasonic wave can be reflected, refracted, and focused as well as the light. Obey the laws of geometric optics. That is, when the ultrasonic ray is reflected from the appearance of a substance, the incident angle is equal to the angle of reflection. When the ray passes through one substance and enters another substance of different density, refraction occurs, that is, the direction of the insertion is changed. The greater the difference in the density of matter, the greater the refraction.
2, Absorption characteristics
As sound waves propagate through various materials, the intensity gradually weakens as the propagation interval increases, because the material absorbs its energy. Regarding the same substance, the higher the frequency of sound waves, the stronger the absorption. Regarding a sound wave with a certain frequency, it absorbs the most harmful when it propagates in a gas, and absorbs weakly when it propagates in a liquid, and absorbs minimally when it propagates in a solid.
3. Ultrasonic energy transfer characteristics
Vibrating feeder ultrasonics have been widely used in various industrial sectors, and the main point is that they have much more powerful power than sound waves. Why is there a powerful power? Because when the sound wave reaches a certain material, the molecules in the material also follow the vibration due to the action of sound waves, the frequency of the vibration and the frequency of the sound wave, and the frequency of the molecular vibration determines the speed of the molecular vibration. The higher the frequency, the greater the speed.
The energy obtained by the material molecules due to vibration is determined by the square of the vibrational velocity of the molecules, in addition to the mass of the molecules. Therefore, if the frequency of the sound waves is higher, the higher the energy of the material molecules, the higher the frequency of the ultrasonic waves. It can be much higher than sound waves, so it can make the material molecules get a lot of energy; in other words, the ultrasound itself can supply enough power for the material.
4. Sound pressure characteristics of ultrasonic waves
When the sound wave is transmitted into an object, the vibration of the material causes the material molecules to contract and dense, which will change the pressure of the substance. Due to the vibration of the sound waves, the additional pressure phenomenon is called sound pressure.
