These waves bounce off as the baby echoes and these echoes are then turned into images on a screen that shows the position of the baby and its respective movements. Hard tissues such as the bone reflect the most sound waves and make the biggest echoes. The images appear white in color on the monitor of the sonographic equipment. Soft tissues appear grey in color and speckled. Fluids such as the amniotic fluid surrounding the baby appear black because the sound waves here do not have any echoes.
