Refraction: Deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (as air) into another (as glass) in which its velocity is different.

Two traveling waves which exist in the same medium will interfere with each other. If their amplitudes add, the interference is said to be constructive interference, and destructive interference if they are "out of phase" and subtract. Patterns of destructive and constructive interference may lead to "dead spots" and "live spots" in auditorium acoustics.\n\nInterference of incident and reflected waves is essential to the production of resonant standing waves.\n\nInterference has far reaching consequences in sound because of the production of "beats" between two frequencies which interfere with each other. \n\nDiffraction: the bending of waves around small obstacles and the spreading out of waves beyond small openings.\n\nRefraction is the bending of waves when they enter a medium where their speed is different. Refraction is not so important a phenomena with sound as it is with light where it is responsible for image formation by lenses, the eye, cameras, etc. But bending of sound waves does occur and is an interesting phenomena in sound\n\nWhen a vehicle with a siren passes you, a noticeable drop in the pitch of the sound of the siren will be observed as the vehicle passes. This is an example of the Doppler effect. An approaching source moves closer during period of the sound wave so the effective wavelength is shortened, giving a higher pitch since the velocity of the wave is unchanged. Similarly the pitch of a receding sound source will be lowered.\n\nLight in the form of a plane wave in space is said to be linearly polarized. Light is a transverse electromagnetic wave, but natural light is generally unpolarized, all planes of propagation being equally probable. If light is composed of two plane waves of equal amplitude by differing in phase by 90°, then the light is said to be circularly polarized. If two plane waves of differing amplitude are related in phase by 90°, or if the relative phase is other than 90° then the light is said to be elliptically polarized.

A mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces) through which they travel and can transfer energy from one place to another without any of the particles of the medium being displaced permanently; there is no associated mass transport.

YES\n\nSince sound waves are mechanical waves they are influenced by the medium in which they travel. But electromagnetic waves such as light and radio waves remain unafftected.

The glass of water is acting as a lens to refract the light coming from the clock.  Refraction is the bending of light rays as they pass through a medium such as water or glass.  Various materials refract light differently.  This fact is the basis for some analytical instruments such as the refractometer.  Also, light of different wavelengths is refracted differently within the same medium.  This, too, is a basis for the above mentioned analytical instruments.  But, the simple one word answer to your question is "refraction".

a push wave in which the particles move in the same direction to that of the wave as opposed to transverse wave in which they move vertical to the wave direction

in waves, therefore, in order to be transmitted it requires some medium to transmit the waves in. That's why sound can't travel through a vacuum such as outer space, for example

Please re-submit your question explaining what medium the waves propagate in.\nDoes ELF refer to Extra Low Frequency radio waves in your question?

I believe it's the percent of light that bounces back and doesnt go through. Like a mirror reflects 95% of light. Dunno could be how much a material bends light, like water, cant remember.

It's called birefringence.\n\nI'd try to explain it myself, but the kind volunteers who submit articles to wikipedia have done it very well already! See the source below - it's under the subtitle "Polarization effects in everyday life".

If you're talking about water waves, if you imagine dropping something in water, the waves propogate as a circle.  But if you're talking about light or sound or radiowaves, etc., it should be a sphere.

there are basically 2 parallel mediums of propagation. air and the outer liquid hemisphere. i expect to see interference also as there will be addition of waveforms.

Any electromegnetic wave, be it light, electricity or x-rays, travels in a wave which has amplitude and wavelength.  For every electromagnetic wave, there is also created a magnetic wave that travels along with it.  If the light wave is going up and down, the magnetic wave will br traveling side to side.  This is the basis for the incredibly simple device, the electromagnet.  If you wind copper wire around a tube, and then pass a current through it, the electricity flows, but also creates a magnetic wave, which will be attracted to iron in the same way a regular magnet would.

The process of polarization is to bend a ray of light as it passes through a lens. To bend a ray of light is to make it less harsh on the eye.

Anisotropic \n \nPertaining to a material whose electrical or optical properties vary with (a) the direction of propagation of a traveling wave or with (b) different polarizations of a traveling wave. Note 1: Anisotropy is exhibited by non-cubic crystals, which have different refractive indices for lightwaves propagating in different directions or with different polarizations. Note 2: Anisotropy may be induced in certain materials under mechanical strain.

When sound (or other waveform of similar shape, like an AC signal) travels through a medium, its intensity diminishes with distance. In idealized materials, signal amplitude is only reduced by the spreading of the wave. Natural materials, however, all produce an effect which further weakens the sound. This further weakening results from scattering and absorption. Scattering is the reflection of the sound in directions other than its original direction of propagation.  Absorption is the conversion of the sound energy to other forms of energy.  The combined effect of scattering and absorption is called attenuation.  Ultrasonic attenuation is the decay rate of the wave as it propagates through material.\n\nAttenuation of sound within a material itself is often not of intrinsic interest. However, natural properties and loading conditions can be related to attenuation. Attenuation often serves as a measurement tool that leads to the formation of theories to explain physical or chemical phenomenon that decreases the ultrasonic intensity. \n\nThe amplitude change of a decaying plane wave can be expressed as:\n\n A = A0*e^(-kz)\n\nIn this expression "A0" is the amplitude of the propagating wave at some location. The amplitude "A" is the reduced amplitude after the wave has traveled a distance "z" from that initial location. The quantity "k" is the attenuation coefficient of the wave traveling in the z-direction. The dimensions of are nepers/length, where a neper is a dimensionless quantity. The term "e" is Napier's constant which is equal to approximately 2.71828. \n\nAttenuation is generally proportional to the square of frequency. Quoted values of attenuation are often given for a single frequency, or an attenuation value averaged over many frequencies may be given. Also, the actual value of the attenuation coefficient for a given material is highly dependent on the way in which the material was manufactured. Thus, quoted values of attenuation only give a rough indication of the attenuation and should not be automatically trusted. Generally, a reliable value of attenuation can only be obtained by determining the attenuation experimentally for the particular material being used.\n\nThis is why higher-frequency signals tend to produce what is called "skin effect" ... basically, the energy isn't there for the wave to penetrate to any significant depth.
