Question

Question to do with intensity and amplitude.

Answer 1

The answer is "amplitude = max amplitude divided by sqrt 2" The actual position, of course, does not matter. but I am having difficulty getting from I = A^2 to the answer

Answer 2

Answer 3

If you are saying this:

\[Amplitude = \frac{Amp_{\max}}{\sqrt{2}}\]

Then that Amplitude is nothing but RMS value of Signal..

Answer 4

What is \(Fig \; \; 5.2\) ?? What is in it??

Answer 5

Fig 5.2

Answer 6

The figure is irrelevant as the position is relative. What I am struggling with is how to algebraically get to the correct answer from \[I = A ^{2}\]
