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
The vibrations that move away from an earthquake's origin are known as seismic waves. There are two main types of seismic waves: primary (P) waves, which are compressional waves that travel fastest through the Earth's interior, and secondary (S) waves, which are shear waves that move more slowly and can only travel through solids. Both types of waves propagate outward from the earthquake's focus, causing the ground shaking associated with seismic events.
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.
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.
Travel agents act as intermediaries who assist clients in booking travel services, such as flights, accommodations, and activities, often providing personalized recommendations and support. In contrast, tour operators create and package travel experiences, organizing all elements of a trip, including transportation, lodging, and guided tours, typically selling these packages through travel agents or directly to consumers. While travel agents focus on individual client needs, tour operators focus on designing comprehensive travel experiences.

State three ideas or topics that could serve as the focus of subject matter in an artwork.
Focus an energetic wave at some matter and see what happens.
"Matter" is a possibility.
