Ultrasound is considered safer than X-rays because it uses sound waves rather than ionizing radiation to create images of the body's internal structures. Ionizing radiation from X-rays can increase the risk of cancer and other health issues with excessive exposure, whereas ultrasound poses no such risks. This makes ultrasound a preferred choice for imaging during pregnancy and for evaluating soft tissues, as it does not carry the same potential hazards associated with radiation.
They are called ultra sonic. They travel faster than sound
X-rays have shorter wavelengths than radio, heat, infra-red, visible light, and ultra-violet.
No, X-rays do not travel at the speed of sound. X-rays are a form of electromagnetic radiation that travel at the speed of light, which is much faster than the speed of sound.
ultra sonic !!
because ultrasound is more safer than audible sound.
Ultrasonic sound refers to sound waves with frequencies higher than the upper threshold of human hearing, typically greater than 20 kHz. These sound waves are used in various applications such as medical imaging, cleaning, and distance measuring due to their ability to penetrate materials and produce detailed results.
The ultra sound having frequency is higher than the human ear can be respond.it is greater than 46khz.
you are having twins.
Facebook IS NOT safer than Bebo.
A blood test can be done at your doctors office. Ultra sound of the uterus can show if there is a a sac forming but the standard urine test will normally turn positive before it is possible to see a sac forming with ultra sound.
False. Ultrasound waves are sound waves with frequencies above the range of human hearing, typically above 20,000 Hz, not less than 20 Hz.
