Answer:
1) Waves are created by energy passing through water, causing it to move in a circular motion.
2) A is a disturbance that transfers energy from one place to another. Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance.
3) Reflection and transmission observed as the energy moves through of the straws reaching the top and reflecting back down. Pushing a straw in the middle will also show transmission and reflection. Some of the energy is transferred to the top, transferred to the bottom and then reflect back to the middle.
