Absolute zero is -273.15 degrees C or -459.67 Degrees F. It is measured on the Kelvin scale as 0 degrees K. I found this: "In all materials, a point is eventually reached at which all oscillations are the slowest they can possibly be. The temperature which corresponds to this point is called absolute zero. Note that the oscillations never come to a complete stop, even at absolute zero." Here: http://www.pa.msu.edu/sciencet/ask_st/012992.html
Amplitude of a longitudinal wave is measured as a change in pressure.
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"
The unit of frequency is "Hertz", abbreviated "Hz".
Also called "cycles". Also called "per second".
specific heat capacity
two inclined planes,double wedge and single wedge
These are the electrodes.
distance between charged particles
Something that transfers thermal energy efficiently is called a conductor.
It can easily be transformed up to a high voltage for power transmission, and back down for home supplies at 120/240 volts.
Refraction is caused by light crossing from one medium to another.
When two or more waves occupy the same space at the same time, an interference pattern is created.
Standing waves are the result of an interference of two waves that are traveling along the same medium in opposite directions.
A magnetic field is produced by any charged particle in motion. It is a fundamental law of nature (as expressed by the electromagnetic force) that a magnetic field will form around any moving charge. We usually think of moving electrons as creating a magnetic field, and this is absolutely correct, but any moving charge can create a magnetic field.
As for what magnetism is, this question has already been answered, and link is provided below to that question.
