What do sound waves travel farther through?

Solids.


Why do waves get smaller as they travel father?

Waves lose energy as they travel farther due to interactions with the medium they are traveling through, such as air or water. This energy loss causes the amplitude (height) of the wave to decrease, resulting in smaller waves.


Do sound waves travel farther in liquid than in gas?

Yes.


Which wave travels farther p-waves or s-waves?

P-waves travel farther than S-waves because they are faster and can pass through both solid and liquid materials. S-waves, on the other hand, are slower and can only travel through solid materials, so their range is more limited.


Suppose both a primary and secondary wave start together and travel for 5 minutes. which wave will travel farther?

Primary waves (P-waves) are faster than secondary waves (S-waves). Therefore, if both waves start together and travel for 5 minutes, the primary wave will travel farther than the secondary wave. This difference in speed is due to the fact that P-waves are compressional waves that can move through solids, liquids, and gases, while S-waves are shear waves that only propagate through solids.


What happens to the wavelength of electromagnetic waves as they travel through a denser medium?

The waves become smaller.


How does the speed of the seismic waves change as they travel farther and farther from the epicenter?

As seismic waves travel farther from the epicenter, their speed generally remains consistent, determined by the type of wave and the properties of the Earth's materials they pass through. However, the amplitude of the waves typically decreases with distance due to geometric spreading and energy absorption by the Earth's materials. Surface waves, which typically travel slower than body waves, may show more significant attenuation as they disperse over greater distances. Thus, while the speed is not affected by distance, the energy and intensity of the waves decrease.


What is it called when waves are farther apart?

When waves are farther apart, it is referred to as having a longer wavelength.


Do waves created by a large disturbance travel faster than waves created by a small disturbance do?

No, waves created by a large disturbance do not necessarily travel faster than waves created by a small disturbance. The speed of a wave depends on the medium through which it is traveling, not on the size of the disturbance that created it.


How could you tell which of two observers was farther from an earthquake epicenter by comparing the arrival times of p waves and a waves for the two locations?

To determine which observer is farther from an earthquake epicenter, you can compare the arrival times of P-waves (primary waves) and S-waves (secondary waves). P-waves travel faster than S-waves, so if one location records P-waves significantly earlier than S-waves, it indicates that the observer is closer to the epicenter. By measuring the time difference between the arrival of the P-waves and S-waves at each observer's location, the observer with the greater time difference is farther from the epicenter.


How could you tell which of two observers was farther from an earthquake epicenter by comparing the arrivaltimes of p and s waves for the two locations?

To determine which observer is farther from an earthquake epicenter, you can compare the arrival times of P-waves (primary waves) and S-waves (secondary waves) at each location. P-waves travel faster than S-waves, so the difference in their arrival times increases with distance from the epicenter. By measuring the time difference between the arrivals of these waves at each observer's location, you can calculate the distance to the epicenter; the observer with the larger time difference will be farther from the epicenter.


Why do am radio waves diffract more than FM radio waves?

AM radio waves have longer wavelengths compared to FM radio waves. This means that AM waves are better able to diffract around obstacles and travel farther distances. FM radio waves, with their shorter wavelengths, are less prone to diffraction and tend to travel in straight lines, making them more susceptible to obstacles blocking their path.
