Homework Statement Sorry if this comes out the wrong way, but I have to translate my problem from norwegian to english... but I'll give it a shot ;) Task 1a was to find some maximal and minimal amplitudes. Those I found: max 30 units and min 10s unit. Task 1b is to use these...

The second answer you gave me seems to be wrong, I found out to crack it on my own. Or... At least i think I did ;) Because the waves are incoherant I have to use the formula: I = I1 + I2 = 3^2 + 4^2 = 25 The intensity for the superposed wave should be 25.

Thank you for your reply, but did you perhaps overlook that it said "9 unit^2"? Anyway. If I now do this your way it'll be like this rigth? 9^2 + 4^2 = 97 And you believed I should square the result so that the final answer would be 97^2. I don't know if this is right, but either way I'm...

First off: Sorry. I'm a Norwegian girl, so my English may not be of very good quality. Now that's said... I have this problem to solve. Only thing is - I don't have a clue how! I'm no good at physics, but unfortunately I have to have this class. Anyway. My problem is this: Task...
