Ultrasound Infrasound From the Giraffe

Infrasound Bats use ultrasound for navigation. Whales use infrasound. Dolphins use ultrasound

 Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing

When two waves that are the same come together to make 1 big wave.

When two opposite waves come together to make a different wave.

When a wave bounces off of something then comes right back.

 When a wave passes through one medium to another.

 When a wave goes around an obstacle.
