The reflection of wave motions may take place in a medium of where they come from.
Harmonics in a mixture will have differing amplitudes decrease the number of harmonics rises.
Yes, heat is the kinetic energy (the vibration modes) of the atoms and or molecules that make up an object.
"Elementary" in this context means that they are not known to be made up of smaller particles. It doesn't mean they can't undergo changes. You can think of the flavors as different excitation states of the same particle - comparable to different vibration modes on the same string. In fact, according to string theory (which is not really a scientific theory yet - more a hypothesis), the fundamental structures in the Universe ARE a type of string, and the different vibration modes of those strings are what gives them their different properties.
Vibration is the frequency of the wave.
The rapid back and forth of air or other matter is the sounds vibration (vibration is the anwser).
Vibration is defined as a mechanical fluctuation from one point to another point. There are mainly two types of vibration involved in vibration analysis: free vibration and forced vibration. Free vibration occurs when an object is turned on, such as a clothes dryer and a lawnmower, and is left to vibrate on its own. Forced vibration happens when an outside object or occurrence vibrates an object. The lawnmower shakes due to an earthquake would be an example of this. Furthermore, vibration monitoring is also another important part of analysis.

THE ULTRASONIC WAVES have constant velocity in homogeneous medium. Many modes of vibration. High resolution,used for flaw detection Sonic beam and highly energetic. reflection and refraction in interface.so elastic

There are no modes.
Two modes is termed bimodal. It is OK to have two modes; both values will be the modes.
Write both modes
This is a very broad question. If you are talking about vibrational modes of a mechanical structure, the usual method is to put accelerometers and vibration meters on it and smack it with a hammer and see which frequencies last longest. If you are talking about a mathematical system, then this is advanced linear algebra that is usually not encountered until Masters and PhD Mathematics or Physics and not something to be answered in a short essay. There may be other senses of the phrase "normal modes". Try getting more specific and re-post your question.
The modes of vibration associated with resonance in extended objects like strings and air columns have characteristic patterns called standing waves. Scroll down to related links and look at "Strings, standing waves and harmonics".
you write both of the modes as your answer
