I need help answering these two questions, can someone please help?

1.How does energy transfer by waves differ from energy transer my moving objects?

2.Define amplitude and frequency as they relate to a wave.
[I know amplitude is the height of a wave and frequency is how many wavelegths pass a given point per second]Would that answer the question?

Thanks!

1. Energy transfered from waves might only be absorbed at certain frequencies. I depends upon what kind of "wave" it is. Light and sound waves are very different.

2. Your expnanation is just fine.

Thanks (:

Of course, I can help you answer those questions!

1. How does energy transfer by waves differ from energy transfer by moving objects?
To understand the difference between energy transfer by waves and energy transfer by moving objects, we need to look at the mechanisms involved.

Energy transfer by waves:
- Waves transfer energy through the oscillation or disturbance of a medium, such as air or water.
- Waves can travel through various media, including solids, liquids, and gases.
- Unlike in the case of moving objects, waves do not require a physical mass to transport the energy. Instead, they transmit energy by transferring the disturbance from one particle to the next.
- Waves can transfer energy over a distance without necessarily transporting matter from one location to another.

Energy transfer by moving objects:
- Energy transfer by moving objects involves the transfer of energy through physical contact or collision between objects.
- In this case, the objects need to have mass and be in motion to carry and transfer energy.
- The energy transferred by moving objects is typically through work done, such as when a force acts on an object to accelerate it or when one object collides with another, transferring its energy.

In summary, energy transfer by waves involves the transmission of energy through the disturbance of a medium without the need for physical mass transport, while energy transfer by moving objects involves the transfer of energy through physical contact between objects.

2. Define amplitude and frequency as they relate to a wave.
Indeed, amplitude refers to the height or maximum displacement of a wave from its equilibrium position. It measures the intensity or strength of the wave. Larger amplitudes indicate louder sounds or brighter lights, for example.

As for frequency, it represents the number of complete waves passing a given point per second. It is measured in hertz (Hz). The higher the frequency, the greater the number of waves passing through that point in a unit of time. Frequency determines the pitch of a sound or the color of light.

Hence, your answer stating that amplitude is the height of a wave and frequency is the number of wavelengths passing a given point per second is correct.
