Is the earth's inner core solid?

Yes the refraction path of the p-wave tells us that the earths inner core is solid.


What is a body wave that can penetrate the earths core?

A seismic body wave that can penetrate the Earth's core is called a P wave (Primary wave). P waves are the fastest seismic waves and they can travel through both solid and liquid layers of the Earth, including the core.

Can sound be refracted?

yes, sound is a wave. waves can be refracted.


What is a direct wave?

A direct wave is a radio wave that travels directly through space without getting refracted by the ionosphere. In other words, it travels straight to the receiving antenna without being refracted.


Why do refracted objects bend?

The light acts as a wave, and the wave accelerates differentially at the border.


The possible source of earths magnetic core is?

The molten iron and medals inside the earths core are the reasons for the earths magnetic core.


What does it mean when a wave refracted?

When a wave is refracted, it changes direction as it passes from one medium to another due to a change in its speed. This bending of the wave is caused by the wave entering the new medium at an angle other than perpendicular to the boundary between the two mediums.


Why is s wave shadow zone larger than the p wave shadow zone?

In simple terms the shadow zone of the S-wave is larger because of the Earth's liquid outer core. The S-wave cannot travel through the liquid outer core but the P-waves get refracted at the boundary between the mantle and the outer core. This is why the S-wave shadow zone is larger than the P wave shadow zone. P waves are refracted at the liquid outer core of the Earth, while S waves are attenuated or stopped entirely. This allows P waves to go "around" the core and reach locations on the far side of the Earth that are within the shadow of the S waves. -- A P-wave is a longitudinal wave with an alternating stretching and compressing motion in the direction of propagation. An S wave is a transverse wave with a vertical motion perpendicular to the direction of propagation. The shadow zone of a P-wave exists from 105 to 143 degrees (epicentral distance). This is caused by P waves meeting the liquid outer core and being refracted. Part of the P wave is also reflected by the outer core and as a result of the two, a shadow zone exists. The shadow zone of an S-wave exists from 105 to 180 degrees (epicentral distance). S-waves cannot travel through liquids at all so rather than being refracted by the liquid outer core and traveling through it, they are totally reflected, resulting in a shadow zone from 105 to 180 degrees.
