Evanescent waves evanescent means "tending to vanish", which is appropriate because the intensity of evanescent waves decays exponentially (rather than sinusoidally) with distance from the interface at which they are formed. Evanescent waves are formed when sinusoidal waves are (internally) reflected off an interface at an angle greater than the critical angle so that total internal reflection occurs

Mechanical oscillations and waves
Mechanical waves a wave pulse is a disturbance that moves through a medium, a periodic wave is a periodic disturbance that moves through a medium.  The medium itself goes nowhere.  The individual atoms and molecules in the medium oscillate about their equilibrium position, but their average position does not change. As they interact with their neighbors, they transfer some of their energy to them

Standing waves standing waves and acoustic resonance
Standing waves two waves with the same frequency, wavelength, and amplitude traveling in opposite directions will interfere and produce standing waves

Vibrations and waves if any object is displaced slightly from equilibrium it will oscillate about its equilibrium position in what is called simple harmonic motion. The most common examples are a mass on a spring, and a simple pendulum

Waves mechanical waves. These are waves that move through some physical medium like air, water, strings, earth, etc. Light and radio waves are not mechanical waves; they are waves in the electromagnetic field. While electromagnetic waves obey many of the same principles as mechanical waves they do have some important differences, Superposition of waves
Waves standing waves, wave reflection, wave refraction, wave interference, speed of waves, travelling waves
Waves a wave is a propagating disturbance in a medium that transmits energy without any net movement of mass
Waves and light
Visible spectrum visible light is made up of electromagnetic waves, vibrations of electric and magnetic fields that propagate through space. In contrast to slow-moving ocean waves to which they are analagous, electromagnetic waves travel at the speed of light: 300 million meters per second
