S waves, transverse waves that oscillate up and down, will travel around objects that they encounter when the objects are larger than the wave lengths. So directly on the far side of the objects they encounter there are no S waves because they have not come back together again. That's the shadow zone.
You can see this in a simply experiment. Put a glass tumbler in the middle of a large flat pan and fill the pan with water. With the water now flat and smooth create a wave by dipping your finger in the water repeatedly. You'll see the waves approach the glass and then wrap around it, but they won't rejoin immediately. There will be still water on the far side of the glass...that's the shadow zone.
What else can I help you with?
The first s-wave arrive at a seismograph station 11 minutes after an earthquake occurred how long after the arrival of the first p-wave did the first s-wave arrive?
The P-wave generally arrives before the S-wave during an earthquake. The time difference between them can help determine the distance to the earthquake's epicenter. In this case, if the S-wave arrived 11 minutes after the earthquake, you would need to calculate the time difference between the arrival of the P-wave and the S-wave to determine how long after the P-wave arrival the S-wave arrived.
What is the region of a compressional wave where particles are close together called?
The region of a compressional wave where particles are close together is called the compression zone. In this zone, particles are crowded closely together, creating areas of high pressure.
What is the part of the wave that is pushed together?
The part of the wave that is pushed together is called the compression zone. In this region, the particles are crowded together, resulting in an increase in pressure and density within the wave.
Is a earthquake s wave a transverse wave?
Yes, an earthquake S-wave (secondary wave) is a transverse wave. It causes particles to move perpendicular to the direction of wave propagation. S-waves are slower than the primary P-waves but can cause more damage due to their side-to-side motion.
What happens to the amplitude when the amount of energy in s wave increases?
When the amount of energy in an S wave increases, the amplitude of the wave also increases. This means that the S wave will have a greater maximum displacement from its resting position as it carries more energy.
Does a primary seismic wave have a larger shadow zone than a secondary wave?
no, an s-wave shadow zone is way larger
Is spandex natural?
An s-wave shadow zone is formed as seismic waves travel through the Earth's body. Which of the following statements does this s-wave shadow zone indicate?
Why is the s-wave shadow zone larger than the p- wave shadow zone?
S waves cannot pass through the outer core. P waves can pass through both outer and inner core.
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.
What is the band around the earth were seismic waves are not detected?
The band around the Earth where seismic waves are not detected is called the "shadow zone." This region exists between 105 to 140 degrees from the epicenter of an earthquake and is caused by the refraction of seismic waves within the Earth's core. It is divided into two main parts, the P-wave shadow zone and the S-wave shadow zone.
What is p wave shadow zone and what causes it?

What is the p wave shadow zone and what cause it?
idfk
Which area of earth is unaffected by both p and s waves?
The shadow zone, located at a distance of 103 to 143 degrees from the earthquake epicenter, is the area on Earth's surface where both P and S waves are completely absorbed and do not arrive due to the core's properties.
Why do S waves not come to the surface beyond the shadow zone?
S waves do not pass through Earth's liquid outer core, which causes a shadow zone on the opposite side of the Earth from an earthquake. The liquid outer core absorbs and blocks S waves, preventing them from reaching the surface beyond the shadow zone.
Why no seismic waves detected at the shadow zone?
In shadow zone, seismograph does not record signals. For P-wave it is b/w 104-145 degress.These earthquake waves exhibit same properties as other waves like reflection, refraction etc.As core has denser matter so P-waves will bend inward and hences they will form a shadow zone. S-waves don't pass through liquid phase, core. So, shadow zone is larger here.
What is the p-wave shadow zone and what causes it?
It is known as the penumbra and the area in total shadow is the umbra
What did studies of the p-wave and s-wave shadows reveal about earths interior?
Studies of p-wave and s-wave shadows, resulting from seismic waves generated by earthquakes, have revealed critical information about Earth's interior. P-waves, or primary waves, can travel through both solids and liquids, while s-waves, or secondary waves, can only travel through solids. The presence of an s-wave shadow zone indicates that a liquid outer core exists, as s-waves do not pass through this region, while the p-wave shadow zone suggests the complexity of the Earth's interior structure. Together, these findings helped establish the layered model of Earth's interior, including the solid mantle, liquid outer core, and solid inner core.
