Amplitude at successive wavefronts?
If so, isn't it against the law of conservation of energy? … So the energy is increasing as the wave is propagating. If we assume amplitude decreases at successive wavefronts, then won't the wave disappear after certain distance? …

Kinetic energy of electron in metals [closed]
Will it be correct to relate temperature of metal with kinetic energy of electron in metal just like as we do to find kinetic energy of gas molecules if we know the temperature by using the following relation … :
$$E=\frac32\ k\ T$$
where $E$ = kinetic energy,
$k$ =Botzmann constant, and
$T$ = absolute temperature? …
