- Homework Statement
- Ans: C
I tried to use the intensity formulae and after manipulating it got an expression which gave me wrong answer.
It seems the areas are not equivalent somehow, any explanation?
- Relevant Equations
- I = P/A
Hi and thanks for welcoming me!Hi @iQadmat and welcome to PF.
How does the intensity depend on the amplitude? You can read the amplitudes of the two waves off the graph and compare.
I got it now, Thanks for your help!The areas are irrelevant. This is a comparison of intensities of two different sources at the same point in space and time. If you must, assume that the two sources are at the same distance from two detectors with identical areas. Compare the detectors' readings. Clearly, wave 2 has greater intensity than wave 1. By what factor?
