Question | Answer | question | answer | Question | Answer |
What is power? | power is the rate at which work is done. | What is wavelength? | Wavelength is the distance from any point on a wave to the next identical point on the same wave. | What is frequency? | Frequency is the number of waves that pass a point in a given amount of time. |
If 26W of power is produced in 15 seconds, how much work is done? | W=PxT W= 26x15 W=390J | What is a longitudinal wave? | A longitudinal wave is when energy is transferred from one object to another. | What is a compression? | A compression is the direction in which waves travel. |
What is work? | Work is the use of force to move an object some distance. | What is a trough? | A trough is the points where the wave is lowest. | What is amplitude? | Amplitude is measured of how far particles in the medium move from their rest position. |
If 78J are produced in 6 seconds, how much power is being done? | P=W divided by T P=78J divided by 6sec P=13 | How many different types of waves are there? | 4. longitudinal, transverse, mechanical, and electromagnetic waves. | What are the materials that a medium can travel in? | Solid, liquid, or gas. |
Can wavelength be measured from one crest to a trough? | No, wavelength is measured from one crest to another crest or one trough to another trough. | What are Hertz? | 1 hertz is equal to one wavelength per second. | What is the wavelength if each crest is 12ft long and troughs are 14ft long? | Wavelength= 12=14=12 wavelength= 38ft long. |
What is a crest? | A crest is the point where the wave is highest. | What is wave speed? | Wave speed is the speed that waves travel. | What is a transverse wave? | A transverse wave is when springs coils move up and down as the wave passes. |
What are mechanical waves? | Mechanical waves are waves that require a medium. | What is a wave? | A wave is a disturbance that travels through a medium. | What is force? | Force is a push or pull exerted on an object on order to change the motion of the object. |
If one hertz = one wavelength per second then how much wavelength is in seven hertz? | Wavelength= 7 per second also. | P=40 watts W= 2,000 Joules T? | T= W divided by P T=2,000 divided by 40 T=50 seconds | P=226 watts T=23 seconds W=? | W=PxT W=226x23 W=5,198J |
What is a medium? | A medium is the material through which a wave can travel. | What is rarefaction? | Rarefaction is the direction in which an object is disturbed. | What are electromagnetic waves? | Electromagnetic waves are traveling of 1 energy source to another. |
