What is the difference between P waves S waves and L waves?
There are two types of seismic waves : Body waves. Surface waves?.Difference between s waves and p waves.
P waves S waves Can move through solids and liquids Can only move through solids Shake the medium in the direction in which they are propagating Shake the medium in the direction perpendicular to which they are moving
What are PS and L waves which type causes the most damage?
Love waves have a particle motion, which, like the S-wave, is transverse to the direction of propagation but with no vertical motion. Their side-to-side motion (like a snake wriggling) causes the ground to twist from side to side, that?s why Love waves cause the most damage to structures.
What is the meaning of L waves?
an earthquake wave that travels around the earth?s surface and is usually the third conspicuous wave to reach a seismograph. Also called long wave . Compare P wave, S wave.
What do P waves and S waves do?
P waves can travel through solids, liquids, and even gases. S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side.
Which body wave is the fastest?
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
What are the 2 main types of body waves?
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
What are the properties of L waves?
L-waves, which are of great importance in earthquake engineering, propagate in a similar way to water waves, at low velocities that are dependent on frequency. S-waves are transverse body waves and thus can only be propagated?
Why is it called Love wave?
The first kind of surface wave is called a Love wave, named after A.E.H. Love, a British mathematician who worked out the mathematical model for this kind of wave in 1911. Because it rolls, it moves the ground up and down, and side-to-side in the same direction that the wave is moving.
What do P, S, and L waves mean?
P, S and L waves refer to Primary, Secondary and Longitudinal waves. L is also the first letter in Love waves. See explanation. Waves are propagated through a medium that is a solid or a fluid ( liquid or gas ). So, there is velocity in this propagation.
How are P waves different from surface waves?
Surface waves can only travel on the surface of the earth. Their frequency is lower than body waves. P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are the fastest seismic waves and can move through solid, liquid or gas. They leave behind a trail of compressions and rarefactions on the medium they move through.
What happens when p and S waves travel through Earth?
The diagrams show what happens when P waves and S waves pass through the Earth. S waves cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium. This causes the waves to travel in curved paths.
Which is the most damaging wave P or s?
Surface waves usually have larger amplitude than the other waves and cause the most damage. A P wave is a longitudinal wave and travels the fastest. It can travel through solids and liquids.
What is the difference between osteopathic and allopathic?
While allopathic schools offer a traditional medical curriculum, osteopathic schools supplement lessons in standard medical sciences and practices with instruction on how to provide touch-based diagnosis and treatment of various health problems, such as circulatory issues and musculoskeletal conditions.
What does an allopathic doctor do?
An allopathic doctor is certified to diagnose and treat illnesses, in addition to performing surgery and prescribing medications. An allopathic doctor can get licensed to perform their duties in any of the 50 states of the United States.
What is difference between allopathic and homeopathic?
The basic difference between Homeopathy and Allopathy is that the former is a modern form of medicine whereas the latter is an ancient form of medication. Candidates who have pursued Allopathy courses are legally not allowed to prescribe Homeopathic medications to their patients.
What does the word allopathic mean?
: relating to or being a system of medicine that aims to combat disease by using remedies (such as drugs or surgery) which produce effects that are different from or incompatible with those of the disease being treated.
Which degree is best for doctor?
The most popular or preferred postgraduate medical degree is Doctor of Medicine (MD) and Master of Surgery (MS). There are a total of 10,821 Master of Surgery (MS), 19,953 Doctor of Medicine (MD) and 1,979 PG Diploma seats in postgraduate medical courses in India.
Which treatment is best homeopathy or allopathy?
Dr Pankaj Aggarwal, senior homeopathy physician, says, ?Homeopathy is way considered best when it comes to safe and sound treatment as it is devoid of any kind side effects or after as in allopath and indulges in to the recovery of the disease or ailment as in Ayurveda where you need many sessions to cure the disease.
Is homeopathy legal in USA?
Licensing. Laws regulating the practice of homeopathy in the United States vary from state to state. Usually, individuals licensed to practice medicine or another health care profession can legally practice homeopathy. In some states, nonlicensed professionals may practice homeopathy.
Which is better Ayurveda or Allopathy?
Undoubtedly, in comparison to allopathic treatment, Ayurvedic treatment is more effective in most of the chronic diseases.
Which is the best definition of Allopathic Medicine?

What kind of Doctor is an allopathic Doctor?
Simply put, an allopathic doctor is one who practices modern medicine. Other terms for allopathic medicine include Western, orthodox, mainstream, or conventional medicine.
When did homeopaths start using the term allopathic?
Homeopaths saw such symptomatic treatments as ?opposites treating opposites? and believed these methods were harmful to patients. Practitioners of alternative medicine have used the term ?allopathic medicine? to refer to the practice of conventional medicine in both Europe and the United States since the 19th century.
Are there any over the counter medications that are allopathic?
