Answer from: Lunablum

The correct answer is "A mechanical wave travels through matter, while an electromagnetic wave travels through empty space".

Explanation:

The difference between a mechanical wave and an electromagnetic wave are as follows:

Electromagnetic waves are produced by the vibrations of the charged particles while the mechanical waves are caused by the wave amplitude.

Electromagnetic wave does not need medium while the mechanical wave need medium to travel. Mechanical wave can travel in solid, liquid and gas. Electromagnetic wave travels in vacuum.

Therefore, a mechanical wave travels through matter, while an electromagnetic wave travels through empty space.

Answer from: 10040813

Considering the definition of wave, mechanical and electromagnetic wave, the correct answer is the last option: "A mechanical wave travels through matter, while an electromagnetic wave travels through empty space."

All waves obey the principle of "transport of energy without displacement of matter".

Then, mechanical waves consist of the propagation of a vibration through a medium carrying energy.

On the other hand, electromagnetic waves are the result of the interaction of electric and magnetic fields. In this type of waves there is transport of energy from one place to another, but they do not require a medium for their propagation and they can travel through space.

So the main difference between mechanical waves and electromagnetic waves is that mechanical waves require a medium (air or water) for their propagation, while electromagnetic waves do not require a medium for their propagation (they can travel through space).

In summary, the correct answer is the last option: "A mechanical wave travels through matter, while an electromagnetic wave travels through empty space."

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.

Aweather forecaster uses doppler radar to predict the track of a storm near the town of meadowlands. when the doppler signal is pointed at the storm from the town's center, the frequencies of the waves appear to be decreasing. what should the weather forecaster predict? a. that the storm will move around the edges of meadowlands without hitting the tosis center o b. that residents should be prepared, because it is impossible to know whether the storm will hit o c. that the storm is moving toward meadowlands and that residents should be prepared d. that the storm is moving away from meadowlands and is not likely to hit the town
