The amplitude is only double at the anti-node of a standing wave at nodes the amplitude is 0. So the total energy in the system is constant (conservation of energy). Besides standing waves don't transfer energy.

Don't wanna scare anyone but...
2 waves of the same frequency create a standing wave (harmonic), DRAMATICALLY increasing the amplitude. Just by doubling the amplitude you will quadruple the energy, quadrupling the amplitude creates a 16-fold increase in the energy carried by the wave - (energy = amplitude squared)
It would require about 100 watts to heat the water enough to pop the corn (NOT 71watts as mentioned above, it takes 150-180 degrees C to pop corn not 100)
So! Who wants to do the math properly , not like that completely wrong mess posted above?
Here's the ratios:

Assume the minimum 0.75 watt magnetron in the cellphone.

Nice find *vintage as well

Fixed but if anyone finds a better version could they let me know.

Got to be a *troll

Mundanest, are you sure that (compared with 5 yrs ago say) the destruction of the US Dollar coupled with the rise in gas price hasn't put us behind you in the petrol buying business?


In 8 years the Dollar has almost halved in value against the Euro, so it is possible but I would still argue that general cost of living is cheaper in the US. This isn't so good if you wanted to move out the country. I have family in the US and the cost for them to come vist here would be astronomical, given exchange rate etc.

I certainly will, however is there some etiquette for doing so that I need to know?

One Nation Under God was added around the same time, all due to Red Terror.

^How about we send you Blair and Brown to take away your freedom. This week Brown will be voting to lock up persons for 42 days without charge. Although I would rather Brown than Bush.

Rottenseed; fair point just pissed off at how outrageously expensive it is.

$4 dollars a gallon and you are complaining, I would kill for $4 a gallon. The cheapest I can get petrol is $8.66 per gallon!! (at latest exchange rate). Bloody government with what relates to about 120% tax.

Just to let you know the Barack Obama on Religion video is dead, but can't be called dead as unsifted.
