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...
