FAQ

Those who are looking for an answer to the question «What equations tell us how fast a wave travels?» often ask the following questions:

### 👋 What travels fast p-wave s-wave surface wave?

Primary waves (P-waves) are compressional waves that are longitudinal in nature. P-waves are pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary"… In air, they take the form of sound waves, hence they travel at the speed of sound.- How fast a wave travels through a medium?
- What are wave equations used for?
- What are wave equations made up of?

### 👋 Affects how fast a sound wave travels?

Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.

What travels on a wave?Light travels by waves. Sound travels by waves.

Photons travel in **harmonic waves** at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the speed of light. The first kind of body wave is the P wave or primary wave.

- WAVE EQUATIONS, WAVE FUNCTIONS AND ORBITALS According to the quantum mechanical concept, electrons in atoms and molecules are considered as ‘standing waves’ or ‘stationery waves’ (similar to vibrations in a stretched string, but in 3 dimensions). Properties of a wave Consider a standing wave in a stretched string.

- The equations are re-graphed, and while the graph of y = x 2 looks nice, it’s difficult to see the graph of the sine wave. The ZoomFit feature can work very well sometimes, but it can’t always read your mind.

- In 1926, Erwin Schrödinger reasoned that if electrons behave as waves, then it should be possible to describe them using a wave equation, like the equation that describes the vibrations of strings (discussed in Chapter 1) or Maxwell’s equation for electromagnetic waves (discussed in Chapter 5). 17.1.1 Classical wave functions

The fastest seismic waves are known as **P waves**. That “p” stands for primary. And early seismologists called them that because these waves were the first to arrive at seismometers from some distant quake. At Earth's surface, P waves travel somewhere between 5 and 8 kilometers per second (3.1 and 5 miles per second).

- A P wave is a longitudinal wave and travels the fastest. It can travel through solids and liquids. An
**S wave**is a transverse wave and travels slower than a P wave, thus arriving after the P wave. S waves can only travel through solids, and as a result do not travel through the liquid core of the Earth.

In a longitudinal wave **the particles are displaced parallel to the direction the wave travels**. An example of longitudinal waves is compressions moving along a slinky. We can make a horizontal longitudinal wave by pushing and pulling the slinky horizontally.

**P waves**are also called compressional waves. These waves can travel through solids, liquids, and gases. P waves can travel through the liquid outer core. An S wave is a different beast. What also travels as a wave?

Light and sound travel in waves as do microwaves.

A transverse wave travels in a straight line but wavers up and down. the high point is the crest and the low point is the trough

All electromagnetic waves travel at the same speed; the speed of light, abbreviated "c". This is approximately equal to 186,000 miles per second or 300,000 kilometers per second.

However, when light travels in matter, it interacts with the atoms and molecules in the material and slows down. As a result, light travels fastest in empty space, and travels slowest in solids. In glass, for example, light travels about 197,000 km/s.

What material travels through a wave?The material that a wave travels through is called **a medium**. A medium can be any form of matter in the state of a solid, liquid, or gas.

The seismic wave that travels the fastest is known as the P-wave.

Wave is a self-sustaining medium of disturbance which does not involve transport of matter itself. A wave has a magnetic and electric field oscillating perpendicular to each other. Ex. of waves water waves, sound waves, light waves etc.

energy, and not matter

- In physics, a wave is a disturbance that travels through
**space and matter**transferring energy from one place to another. When studying waves it's important to remember that they transfer energy, not matter.

P waves travel fastest.

**A transverse wave** is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.

Both P and S waves are called body-waves because they move within the Earth's interior. Their speeds vary depending on the density and the elastic properties of the material they pass through, and they are amplified as they reach the surface. The third type of wave, and the slowest, is **the surface wave**.

If you're refering to earthquakes, waves that travel along the surface are called surface waves.
