The waves that are slower that those that originate at the focus are called secondary waves or S-waves. They are shear waves that are transverse in nature.
Seismic waves are the earths crust vibrating. there are two types of waves P-waves and S-waves (Primary and Secondary) Primary waves travel faster than s waves and can travel through solid and liquid, S-waves can only travel through solids
Any lens (other than those used exclusively for close up work) can focus on infinity, which is simply put, is the distant horizon. Whether or not you can make out the small detail is another matter.
Your timing belt has probably worn out, or broken, and has jumped timing.
Rock under stress breaks at the focus, releasing energy and vibrations called seismic waves, which travel away from the focus, through Earth's interior, and across the surface. The three types of seismic waves are: Primary waves: The first to arrive at seismographs Secondary waves: The second to arrive at seismographs Surface waves: The last and most severe to arrive at seismographs
p waves
P-waves, which may also be known as primary (as they arrive travel faster than other types of seismic waves and so are recorded on a seismometer first) or pressure waves as they propagate by the compression of matter.
Surface waves are slower than body waves like P-waves and S-waves because they travel along the Earth's surface instead of through the interior. Surface waves typically cause the most damage during an earthquake due to their combination of horizontal and vertical motion.
The waves that are slower that those that originate at the focus are called secondary waves or S-waves. They are shear waves that are transverse in nature.
Surface waves do not originate from the focus. These waves are created when seismic energy reaches the Earth's surface and move horizontally along it, causing the ground to move in a rolling motion.
The center of a seismic wave is called the focus or hypocenter. This is the point within the Earth where the seismic waves originate.
Seismic waves move in all directions away from the point of earthquake origin, traveling through the Earth's interior in a wave-like pattern. The waves can be categorized as body waves (P-waves and S-waves) that travel through the Earth's interior and surface waves that travel along the Earth's surface.
State three ideas or topics that could serve as the focus of subject matter in an artwork.
Seismic waves are the earths crust vibrating. there are two types of waves P-waves and S-waves (Primary and Secondary) Primary waves travel faster than s waves and can travel through solid and liquid, S-waves can only travel through solids
"Matter" is a possibility.
Focus an energetic wave at some matter and see what happens.
Seismic waves travel in all directins radiating out from the Earthquake's epicenter and/or focus.
