An eccentric contraction is one that causes a muscle to lengthen.
isotonic
This process is called contraction. Muscles shorten or contract to produce movement.
A muscular contraction that causes a muscle to shorten is called a concentric contraction. A concentric contraction is a type of isotonic contraction.
A cramp is a sudden over-shortening of a muscle. Cramps are involuntary and, often, severe. They can be extremely painful.
Because when you pluck/strum etc a string it vibrates, and this causes the sound. If you lengthen or shorten the string, the pitch changed (longer:lower, shorter:higher) Hope this helps!
Contraction phase
The vocal cords lengthen ad you get taller
Because when light enters a new substance, its speed changes. In order for the law demonstrated in the equation (frequency = speed/wavelength) to remain the same, the wavelength of the light particle/wave must shorten or lengthen. This change causes the wave to slightly refract to one side or the other.

Nerve impulses that originate in the central nervous system cause muscles to contract. Muscle fiber generates tension during the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same.

It causes the wavelength to shorten
due to contraction of heart
