First of all, we need to understand the nature of ultrasound. Ultrasound itself is a form of wave. In essence, it is a response trend of object wave frequency. When playing an instrument, tapping a door or tapping a table top, the vibration of sound will cause the rhythmic vibration of the medium-air molecules, making the surrounding air change in density, forming a dense longitudinal wave, which generates sound waves. Therefore, the generation of waves must depend on the medium.

Why should ultrasonic scanning microscope add water?

The higher the density of the medium, the smaller the distance between molecules, the faster the transmission speed of sound waves, which also explains why the propagation speed of sound waves in solids and liquids is greater than that of sound waves in air.

Now let's get back to the point, why should we add water to the water immersion ultrasonic scanning microscope? The basic principle of ultrasonic scanning microscope is a system that is mostly used to evaluate the target object by using the echo signal. By measuring the time interval between the ultrasonic signal receiving and sending, the distance between the target object and the ultrasonic transducer can be determined, and the accurate imaging judgment can be achieved through computer calculation. In terms of its basic properties, the transmission of ultrasonic depends on the medium water, which is also superior to other media in terms of the efficiency of ultrasonic transmission speed. Because there will be different levels of impurities in ordinary water, it is generally recommended to add ionic water to the immersion ultrasonic scanning microscope produced by China and Wuzhizhuying.
