Ultrasonik refers to sound waves that have a frequency higher than the upper limit of human hearing, typically above 20,000 hertz. These sound waves are used in various applications, including medical imaging, cleaning delicate instruments, and even in pest control. In medicine, ultrasonik technology is commonly used in ultrasound imaging, allowing doctors to visualize internal organs and monitor pregnancies. Additionally, ultrasonic cleaners utilize these high-frequency sound waves to remove dirt and contaminants from items like jewelry and electronic components, making them effective for thorough cleaning without damage.
