We can determine the velocity of a wave when given the and the wavelength. frequency
amplitude
crest
equilibrium

velocity = frequency * wavelength

Given the wavelength one must also have the frequency.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
