| Question | Answer |
| The direction in which a transverse wave travels is | at right angles to the disturbance. |
| An example of a longitudinal wave is | a sound wave |
| What is a statement that best defines a medium of a wave? | A material through which a wave travels. |
| As you increase the amplitude of a wave, you also increase the | energy. |
| To identify the amplitude of a longitudinal wave, you would look for areas of | crests. |
| What is a statement which describes the relationship between frequency and wavelength? | When frequency increases wavelength decreases. |
| For a wave refraction to take place, a wave must | enter a new medium. |
| What is a setup in a wave tank, that would enable you to demonstrate diffraction? | Water and a barrier with a small gap. |
| Two waves come together to form a new, smaller wave. This is called | destructive interference. |
| Do you think the following is an accurate definition of a medium? Explain why or why not. A medium is any solid through which waves travel. | No, because a medium doesn't have to be a solid. |
| Picture a pendulum. The pendulum is swinging back and forth at a steady rate. How could you make it swing higher? How is swinging a pendulum like making a wave? | You could make it swing higher by pulling the pendulum higher. It represent a wave because it shows the transfer of energy from one place to another. |
| What might happen to an ocean wave that encounters a gap or a hole in the cliff along the shore? | The ocean wave would diffract and spread out in all different directions, when it goes through the gap. |
| An ocean wave has a wavelength of 9 m and a frequency of 0.42 wavelengths/s. What is the wave's speed? | 3.87 hrtz |
| Describe three situations in which you can predict the behavior of waves. | Reflection- When you stand at a mirror and the light bounces of the mirror and into your eyes. Refraction- When you put a straw into a glass of water, the straw bends at an angle other than 90 degrees. Diffraction- When you have a tv on in one room and the door is open, in the other room, the sound waves spread out in all directions. |
| What is the definition of Amplitude? | Amplitude is the distance between the middle of a wave to the crest or trough of the wave. |
| What is the definition of diffraction? | Diffraction is when there is a surface with a gap in it and when the waves pass through the gap, they spread out in all directions. |
| What is the definition of frequency? | Frequency is the number of waves passing a certain place in a certain amount of time. |
| What is the definition of medium? | A medium is any substance a wave moves through. |
| What is the definition of a crest? | A crest is the top, or the peak, of a wave. |
| What is the definition of interference? | Interference is the meetig and the combining of waves. |
| What is the definition of reflection? | Reflection is the bouncing back of a wave after it hits a surface it cannot pass through. |
| What is the definition of a trough? | A trough is the lowest point, or valley of a wave. |
| What is the definition of refraction? | Refraction is when a wave goes through another medium and bends at an angle other than 90 degrees. |
| What is the definition of wavelength? | A wavelength is the distance between each waves trough and trough, or the distance between each waves crest and crest. |
