How do ultrasound waves show us what an unborn baby looks like?
They send high-frequency sound waves into the body, which bounce off internal structures to form an image.
They emit low-frequency vibrations that pass through tissues and create a visual outline of the baby.
They release tiny pulses of light that reflect off the baby’s body to generate an image.
They send electrical signals through the body that map the shape of internal structures on a screen.

Why is a transverse wave called a transverse wave?
Because the particles of the medium move in the same direction as the wave.
Because the particles of the medium move at a right angle to the direction of the wave.
Because the wave transfers energy without moving the particles of the medium.
Because the wave moves only in circular motions through the medium.
