the elastic is medium
An ultrasound wave (or any other sound wave) is mechanical energy, and can be said to be a mechanical wave. Waves are not elastic. The term elastic may be applied to the medium through which they travel. There are compression and shear forces (among others) that work on the medium, and the medium may present a more or less elastic response.
One type of mechanical wave motion in an elastic medium is longitudinal waves. In longitudinal waves, the particles of the medium move parallel to the direction of the wave propagation. An example of longitudinal waves is sound waves traveling through air.
The medium's properties that affect the speed of a transverse wave include its density and elastic properties. In general, waves propagate slower in denser media and faster in more elastic media. The interaction between these two factors determines the speed at which the wave can travel through the medium.
The speed of sound in a medium is affected by the density and elasticity of the medium. Sound travels faster in denser and more elastic mediums, such as solids, compared to less dense and less elastic mediums, such as gases. The speed of sound is typically highest in solids, lower in liquids, and slowest in gases.
the elasticity of an element is derived from the charge keeping them together, so yes air is an elastic medium but not a good one.

Sound. Heat, light, radar & x-rays are electromagnetic.

The speed of a wave through its medium is determined by the medium's properties, such as its density and elasticity. In general, denser and more elastic mediums propagate waves faster. This speed is also influenced by the wavelength and frequency of the wave.
The speed of a wave is determined by the medium through which it is traveling and the properties of that medium, such as its density and elasticity. In general, waves travel faster in more dense and less elastic mediums.
Waves travel slowest in mediums that offer more resistance to their propagation, such as solid materials like rock or metal. The speed of waves is determined by the medium's density and elasticity - the denser and less elastic the medium, the slower the waves will travel.
A sound wave's structure, by definition, is a longitudinal one. More specifically, it is "a longitudinal wave in an elastic medium."
The speed of sound in a medium depends on the properties of that medium, such as its density and elasticity. In general, sound travels faster in mediums that are denser and more elastic. This is because the particles in the medium can transmit the sound waves more effectively.
You use 1" more than the waist you're sewing for. This allows for a 1" overlap to sew the elastic together securely. Answer two: Per this entry from Threads Magazine online: The length of elastic should be shorter than the waist seam (after seams and darts are sewn). How much shorter depends on the combination of fabric, lining and elastic. On lightweight fabric with lightweight lining, use clear elastic, and pull the elastic gently as you sew it in place. If the fashion fabric is corduroy or cotton twill with a medium lining, use braided elastic, and stretch the elastic more as you sew it in place because heavy or firm fabrics put more pressure on the elastic. http://www.threadsmagazine.com/item/3740/how-to-shop-for-elastic
