| How does an ocean wave transfer energy across the ocean? | An ocean wave transferes energy across the ocean by travelling many kilometers without the water itself moving, what is moving is the energy. |
| How are all mechanical waves similar? | Mechanical waves are all similar because they all transfer energy through matter. |
| How do stadium waves differ from a real ocean wave? | Ocean waves use water and stadium waves use people. |
| What is a transverse wave? Can you give two examples? | A transverse wave is a wave where the direction of the wave is parallel or at right angles to the disturbance. Two examples are water waves and when you make a disturbance in a rope in an up and down motion. |
| Describe how forces start waves. | Forces start waves because forces trigger a disturbance and a disturbance is what causes a wave. |
| Explain how a wave can travel through a medium and yet the medium stays in place.T | The medium stays in place because the energy in the wave is travelling, not the whole amount of matter. |
| Describe two ways in which waves travel, and give an example of each. | One way in which waves travel are longitudinal waves, where the direction of the waves is the same as the direction of the disturbance. An example of a longitudinal wave is a sound wave. Another way a wave travels is a transverse wave, which is when the direction of the wave is perpendicular or at right angles to the direction of the disturbance. An example of a transverse wave is a water wave. |
| Does water moving through a hose qualify as a wave? Explain why or why not. | No because the matter is moving the whole way, and even though energy is being passed through the water, the water is still moving the whole way. |
| Suppose you drop a cookie crumb into your milk. At once, you see ripples spreading across the surface of the milk. What type of waves are these? What was the disturbance? | The type of wave was a transverse wave because the water waves were perpendicular to the disturbance. The disturbance was the cookie crumb falling into the milk. |
| Suppose you had a rope long enough to extend several blocks down your street. If you were to start a wave in that rope, do you think it would continue all the way down the street? Explain why or why not. | I don't think the wave would be able to continue all the way down the street because not enough energy would be passing through, for it to last that long. |
