Am I wrong, or is my professor? Intensity Question

Click For Summary
The discussion centers on a conceptual question regarding sound waves transitioning from air to water, specifically about changes in intensity, frequency, and velocity. The original poster believes that the intensity of the sound wave increases in water, while their professor argues that it does not, citing the need for additional energy to increase intensity. Participants clarify that intensity measures the rate of energy transfer, not the total energy, and that frequency remains constant during the transition. The conversation also touches on the implications of poorly posed questions in educational settings and the importance of accurately interpreting problems. Ultimately, the consensus leans towards the professor's position that intensity does not increase when sound moves from air to water.

The professor was right.

I am not sure what you would find compelling, but your reasoning is fundamentally flawed. You based your claim on an equation with many variables, but considered only the effect of one variable. What about all of the others? You cannot use that equation to claim an increase in intensity if you don't know how all of the variables change.

The professors explanation was correct and simple.

You have but you just don't seem to have accepted / understood it. Read it all again in the frame of mind that we (and your Professor) could actually be right. :smile:
