Gelombang transversal

Gelombang Transversal
Gelombang dalam perambatannya mempunyai arah dalam perambatannya, begitu juga dengan getaran (ingat pengertian gelombang, bahwa gelombang adalah getaran yang merambat). Seperti yang dijelaskan pada postingan sebelumnya tentang pengertian gelombang, bahwa berdasarkan arah rambatannya
Untuk mengetahui apa pengertian gelombang transversal coba lakukan percobaan sederhana berikut. Kamu ambil sebuah tali dan pita, kemudian tali tersebut kamu pegang ujungnya dan ujung yang lain suruh teman kamu untuk memegannya. Sementara pita tersebut kamu ikatkan pada tengah-tangah tali. Kemudian hentakan ujung tali yang kamu pegang. Apa yang terjadi pada tali tersebut? Apa yang terjadi pada pita yang kamu ikatkan pada tengah-tengah tali?
Ketika kamu menghentakkan ujung tali sementara ujung yang lainnya dipegang temanmu, akan terbentuk gelombang yang menjalar dari ujung yang kamu pegang ke ujung yang dipegang temanmu. Arah gelombang tersebut adalah mendatar atau horizontal.
Pita yang diikatkan pada tali akan mengalami gerakan naik dan turun setiap kali gelombang melewatinya. Pita tidak ikut merambat, tetapi hanya bergerak ke atas kemudian ke bawah jika gelombang telah melewatinya. Gerakan pita adalah vertikal.

Ternyata, gelombang pada tali merambat secara horizontal dan arah getarannya vertikal. Dengan demikian arah perambatan gelombang dan arah getarannya saling tegak lurus. Gelombang seperti ini disebut dengan gelombang transversal. Jadi, pengertian gelombang transversal adalah gelombang yang arah perambatannya tegak lurus terhadap arah getarannya.


Istilah-istilah dalam gelombang transversal :
Puncak gelombang adalah titik tertinggi pada gelombang (misal b dan f)
Dasar gelombang adalah titik-titik terendah pada gelombang (misal d dan h)
Bukit gelombang adalah lengkungan obc atau efg
Lembah gelombang adalah cekungan cde atau ghi
Amplitude (A) adalah nilai mutlak simpangan terbesar yang dapat dicapai oleh partikel (misal b b1 atau d d1)
Panjang Gelombang (λ) adalah jarak antara dua puncak berurutan (misal bf ) atau jarak antara dua dasar berurutan (misal dh)
Gelombang transversal merambat pada medium padat karena gelombang ini membutuhkan medium yang relatif kaku untuk merambatkan energi getarnya. Jika medium tempat merambat tidak kaku, partikel medium akan saling meluncur. Dengan demikian, gelombang transversal tidak dapat merambat dalam medium fluida (zat cair dan gas).
Gelombang transversal dapat diperoleh dengan menarik sebuah slinki dalam arah horizontal, kemudian menggetarkan ujung slinki ke atas dan ke bawah, energi getaran tersebut akan dipindahkan dari ujung yang satu ke ujung yang lain dan terbentuklah gelombang. Pada saat energi getaran berpindah, medium tempat gelombang merambat bergerak ke atas dan ke bawah sehingga gerak medium tersebut tegak lurus terhadap gerak gelombang.

Transversal Waves
In the direction of wave propagation has the propagation, as well as vibration (remember understanding waves, that waves are vibrations that propagate). As explained in the previous post about understanding the waves, that based on the direction rambatannya.

To find out what the terms of transverse waves trying to do the following simple experiment. You grab a rope and ribbon, then you hold the rope end and the other end to tell your friends memegannya. While the ribbon you tie the hands of the middle-rope. Then snap the end of the rope you hold. What happens to the rope? What happens to the ribbon you tie in the middle of the rope?
When you stomp end of the rope while the other end is held by friends, will form a wave that propagates from the tip to the end that you hold your friend held. The wave direction is flat or horizontal.
Ribbon tied around the rope will experience movement up and down each time the wave passed. Tape does not come creeping, but only move up and then down when the wave has passed. Tape motion is vertical. 

Apparently, the wave propagates horizontally on ropes and vertical vibration direction. Thus the direction of wave propagation and vibration directions perpendicular to each other. Such a wave is called a transverse wave. Thus, the notion of a transverse wave is a wave whose propagation direction perpendicular to the direction of vibration.

In terms of transverse waves:
Wave crest is the highest point on the wave (eg, b and f)
Basic wave is the lowest points on the wave (eg, d and h)
Arch OBC hill or wave is efg
Valley of the wave is hollow CDE or ghi
Amplitude (A) is the absolute value of the largest deviation that can be achieved by particles (eg b or d d1 b1)
Wavelength (λ) is the distance between two successive peaks (eg bf) or the distance between two consecutive base (eg dh)
Transverse waves propagating in a solid medium for these waves need a medium that is relatively stiff for merambatkan vibration energy. If the propagating medium is rigid, medium particles will each slide. Thus, transverse waves can not propagate in a fluid medium (liquid and gas).
Transverse waves can be obtained by drawing a slinki in the horizontal direction, then vibrate the tip slinki up and down, the vibration energy is transferred from one end to the other and formed a wave. At the time of vibrational energy to move, the medium where the waves propagate upward and downward so that the motion of the medium is perpendicular to the wave motion.
