what is the difference of primary and secondary waves?

Secondary waves rock small buildings back and forth as they pass. Secondary waves can travel through rock, but unlike primary waves they cannot travel through liquids or gases. ... As a primary wave passes through a material, the volume and density of the material change slightly.

Through the body of the Earth these are called P-waves (for primary because they are fastest) and S-waves (for secondary since they are slower). However, where a free surface is present (like the Earth–air interface) these two types of motion can combine to form complex surface waves.

But the most important difference is that primary data is factual and original whereas secondary data is just the analysis and interpretation of the primary data. While primary data is collected with an aim for getting solution to the problem at hand, secondary data is collected for other purposes.

The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water.

Several common wave characteristics include frequency, period, wavelength, and amplitude. There are two main type of waves, transverse waves and longitudinal waves.

For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium. EM waves travel at the speed of light 3x10^8 m/s, whereas mechanical waves travel slower.

There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water.

Both have a crest and a trough. True as both electromagnetic and mechanical waves have WAVE NATURE. Both move due to particles bumping into each other.

Longer wave length, lower frequency waves (heat and radio) have less energy than shorter wave length, higher frequency waves (X and gamma rays). Not all electromagnetic (EM) radiation is ionizing. Only the high frequency portion of the electromagnetic spectrum which includes X rays and gamma rays is ionizing.

Primary waves P-waves are pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary". These waves can travel through any type of material, including fluids, and can travel nearly 1.7 times faster than the S-waves.

The difference between a primary and a secondary market is that a primary market is one in which a stock is being offerred directly from a company to investors for the first time. ... In contrast to this, a secondary market is a market in which investors are buying stocks from and selling stocks to one another.

For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.

The key difference between primary and secondary standard solution is that primary standard solution has a high purity and less reactivity whereas secondary solution has a less purity and high reactivity. ... Standard solutions have accurately known concentrations and we prepare these solutions using standard substances.

There are two types of seismic wave, namely, 'body wave' and 'surface wave'. There are two kinds of body waves: primary (P-waves) and secondary (S-waves). Surface waves are analogous to water waves and travel just under the Earth's surface. They travel more slowly than body waves.

Earthquakes produce three types of seismic waves: primary waves, secondary waves, and surface waves. ... Scientists learn about Earth's layers by studying the paths and speeds of seismic waves traveling through Earth. Primary Waves. The fastest seismic waves are called primary waves, or P waves.

EM waves do not propagate in a medium, whereas mechanical waves need one to exist. For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium.

The frequency of a wave depends on how fast the wave is moving. ... If the other set has a shorter wavelength, it will have a higher frequency (less time between waves). Wavelength and frequency go opposite of each other. Shorter wavelengths mean higher frequencies, while longer wavelengths mean lower frequencies.
