Reflected sound waves
The first uses the second, so they are not really "similar".
similar shape 1-1 mapping
Nothing; male and female fetuses have similar heart rates.
Ultrasound technology was first discovered by Paul Langevin and his assistant in 1916. Sonar, a similar technique, was then developed during World War I. The medical applications of ultrasound were later developed in the 1950s and 1960s.
Ultrasound is sound which has a frequency higher than that of audible sound.( like radar )ADDED: Not like radar. That uses radio waves, although sonar and radar principles are similar.
bats have bad eyesight so they use their echo ultrasound and big ears to reflect sound and tell if there is something in front of them so that they can see similar to how a cats wiskars work
The definition of Ultrasound is very short wavelengths of sound used in a similar way to x-rays. The reason that ultrasound is used is the fact that sound does can be used for getting moving pictures of internal bits of the body that x-rays can show as accurately
Runtime memory mapping pertains to any given geographical?æinformation that is not officially stored memory. It is quite similar to real time in that it is the here and now status. Often times it is fed from satellite.?æ
Echocardiography is a test, similar to an ultrasound, that looks at the condition of the heart. It can detect heart problems like blood clots and problems in the aorta.
An endorectal ultrasound involves inserting a probe into the rectum to obtain images of the rectal wall and surrounding tissues, primarily used to assess rectal diseases or conditions. In contrast, a transrectal ultrasound is specifically focused on imaging the prostate gland and surrounding structures in men, often used for prostate cancer evaluation or biopsies. While both procedures utilize similar technologies, their primary applications and target areas differ.
In many countries, the central government agency responsible for the mapping and exploration of minerals is the Ministry of Mines or a similar department. These agencies oversee the regulation and development of mineral resources, ensuring sustainable extraction and maximizing economic benefits. They often collaborate with specialized geological surveys or organizations to conduct mapping and exploration activities.
Bats have the ears which remind the radar and their function is also similar. (Only instead of electromagnetic impulses they receive ultrasound impulses.)
