Types of wavesThe wave is about a form of movement. The waves can be classified by various characteristics, as follows:1. classified by the characteristics of the medium 1.1 mechanical waves (Mechanical wave) is the wave motion by virtue of the medium, which may be solid, liquid or gas pedals. Examples of mechanical waves include: Sound waves Water surface wave Waves on a string, etc. 1.2 electromagnetic waves (Electromagnetic waves) as waves moving without relying on intermediaries can move in a vacuum, like light waves. Radio and television waves. Gamma waves, microwaves, x-rays, etc. 2. a classification according to the movement. 2.1 transverse waves (Transverse wave) is a particle of the medium wave motion in a direction perpendicular to the direction of motion of the wave. Examples of transverse waves include: Electromagnetic waves. 2.2 longitudinal waves (Longitudinal wave) is a particle of the medium waves moving in the same direction, the vertical motion of waves. Examples of longitudinal waves include sound waves. 3. classification according to the wave 3.1. wave (Pulse wave), medium wave is caused by disturbed sources only once. 3.2 continuous wave (Continuous wave) is the wave that is caused by disturbed the continuous, rhythmic source. Components of the wave.Hendrix wave (Crest) is the highest position of the wave, or where there is a maximum positive displacement.The belly is the wave (Crest) is the lowest position of the wave, or as a position of maximum displacement in a negative way.Amplitude (Amplitude) is the maximum displacement distance, both positive and negative.The wavelengths (wavelength) is the length of one wave ball is equal to the distance between the ridges and waves or wave belly next to them. Wavelength, symbolized by the metre (m) Frequency (frequency) refers to the number of waves that move at any position in one unit of time, symbolized by the cycles per second (s-1), or Hertz (Hz). Lessons (period), the moment the wave moving through any place one wave is represented by the symbol (s) per second. The speed of the wave (wave speed) from the product between wavelength and frequency. The properties of waves (wave properties).All types of waves, the show is a reflection of four treasures. Refraction interference and diffraction Mirroring. (Reflection), caused waves to impact obstacles and change direction back to the original outdoor. Refraction (refraction) caused waves moving through different intermediaries make speed changes to. การเลี้ยวเบน (diffraction) เกิดจากคลื่นเคลื่อนที่ไปพบสิ่งกีดขวาง ทำให้คลื่นส่วนหนึ่งอ้อมบริเวณของสิ่งกีดขวางแผ่ไปทางด้านหลังของสิ่งกีดขวางนั้น การแทรกสอด (interference) เกิดจากคลื่นสองขบวนที่เหมือนกันทุกประการเคลื่อนที่มาพบกัน แล้วเกิดการซ้อนทับกัน ถ้าเป็นคลื่นแสงจะเห็นแถบมืดและแถบสว่างสลับกัน ส่วนคลื่นเสียงจะได้ยินเสียงดังเสียงค่อยสลับกัน
