Physics Waves Query!

[Zishi]

Hello, just wanted to ask that if Energy of a Wave is directly proportional to square of the amplitude?

I'm very much confused about it, please reply ASAP!

 

[Mhm]

Yes ... Since Intensity of a wave is like power and is directly prop. to the square of amplitude ... So energy is too!

Oh, well, thanks! Doesn't know why "Understanding Physics for A level" states it wrongly. :S
