Ultrasound waves from an ultrasound machine are reflected back differently to the machine according to what they reflect off. They will reflect differently off muscle, fat and bone.

Ultrasound machines have to send very low-pitched sound waves into the body of the person being examined. Piezoelectricity is involved in making these low-pitched sounds.

Certain flowers like potato and tomato plants have a strange anther. Their pollen doesn’t just fall off the anther. A bumblebee grabs the flower with its legs and begins violently shaking to get the pollen.

Elk vocal cords have a similar size and weight of vocal cords as lions, yet their call is a high-pitched bugle sound.
