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.

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?
What are shadow zones and why do they exist?
The shadow zone refers to an position that does direct P waves from angular distances of an given earthquake.
When p wave bend while traveling through earth's core what happen when arrive at the shadow zone?
When the P wave bends while traveling through the Earth's core, it changes speed and direction due to the difference in density between the outer and inner core. This bending causes a shadow zone on the opposite side of the Earth from the seismic source, where P waves are significantly weakened or not detected due to refraction and reflection within the core.

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.
Does a primary seismic wave have a larger shadow zone than a secondary wave?
no, an s-wave shadow zone is way larger
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 the p-wave shadow zone and what causes it?
It is known as the penumbra and the area in total shadow is the umbra
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.

P wave spend while traveling through Earth's core and then arrive at the shadow zone?
P waves travel through the Earth's core faster than S waves, causing them to slow down and bend as they pass through the outer core. This bending results in P waves creating a shadow zone on the opposite side of the Earth from the seismic event, where they are not detected by seismometers for a certain distance.
