Description

In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance of one or more quantities. Periodic waves oscillate repeatedly about an equilibrium (resting) value at some frequency. When the entire waveform moves in one direction, it is said to be a travelling wave; by contrast, a pair of superimposed periodic waves traveling in opposite directions makes a standing wave. In a standing wave, the amplitude of vibration has nulls at some positions where the wave amplitude appears smaller or even zero. Waves are often described by a wave equation or a one-way wave equation for single wave propagation in a defined direction.

তরঙ্গ বা ঢেউ হলো এক ধরনের কম্পনরত আন্দোলন যা এক স্থান থেকে অন্য স্থানে শক্তি সঞ্চারিত করে। মাধ্যম ব্যতিরেকে তরঙ্গ শূন্যস্থান দিয়েও সঞ্চারিত হতে পারে। এ ধরনের তরঙ্গ হলো তাড়িতচ্চৌম্বক তরঙ্গ এবং মহাকর্ষীয় তরঙ্গ। জড় মাধ্যমের কণার আন্দোলনের ফলে বা কোনো বস্তুর কলাকৌশলের ফলে যে তরঙ্গ সৃষ্টি হয় তাকে যান্ত্রিক তরঙ্গ বলে। এই তরঙ্গ মাধ্যমের কণার কোন স্থায়ী ঘটায় না, বরং এই তরঙ্গ মাধ্যমের কণাগুলোর স্পন্দন বা কম্পন দ্বারা সঞ্চালিত হয়।সুতরাং যান্ত্রিক তরঙ্গের সঞ্চালনের জন্য মাধ্যমটি স্থিতিস্থাপক এবং অবিচ্ছিন্ন হওয়া প্রয়োজন।
