私たちはあらゆる波動に囲まれています。地球は地盤から、海面は絶え間なく揺れ動き、音は陸、海、空気に反響します。私たちの体内に目を向ければ、脳や器官もそれぞれに波動で形成されていますし、宇宙空間はあらゆる電磁放射線を包容しています。力学的な波、量子波、最近観測可能になった重力波も波動です。波動の種類、その源、効果、用途、そして反射、回折、干渉、偏光など波動がもたらす現象を取り上げ解説します。
We live in a world of waves. The Earth shakes to its foundations, the seas and oceans tremble incessantly, sounds reverberate through land, sea, and air. Beneath the skin, our brains and bodies are awash with waves of their own, and the Universe is filled by a vast spectrum of electromagnetic radiation, of which visible light is the narrowest sliver. Casting the net even wider, there are mechanical waves, quantum wave phenomena, and the now clearly detected gravitational waves. Look closer and deeper and more kinds of waves appear, down to the most fundamental level of reality.
This Very Short Introduction looks at all the main kinds of wave, their sources, effects, and uses. Mike Goldsmith discusses how wave motion results in a range of phenomena, from reflection, diffraction, interference, and polarization in the case of light waves to beats and echoes for sound. All waves, however different, share many of the same features, and, as Goldsmith shows, for all their complexities many of their behaviours are fundamentally simple.
