Maxima of Two Waves Beating Together: 0 or Infinity?

AI Thread Summary
The discussion centers on determining the maximum amplitude of two waves of equal intensity, denoted as "I," when they beat together. The consensus is that the maximum cannot be infinity, as that would not align with the principles of wave interference. Instead, the maximum amplitude is derived from the constructive interference of the two waves, which can be calculated based on their intensities. The correct approach involves understanding the concept of "beats" and how wave amplitudes combine. Ultimately, the maximum amplitude is a finite value, not zero or infinity.

Two waves of equal intensities "I" beat together, what is the maxima of the beat equal to ?
Is it 0 or infinity,or other answers... I just couldn't get it

To get the best out of these forums, you should try to show your working - in this case, that would be your reasoning. eg. why would you think that the maxima of the beat could be zero or infinity?

To tackle this sort of problem, you need to go back to basics: what is meant by the beat" in this context?
 
What is the highest amplitude that two waves of intensity I could add up to?

(Infinity is certainly NOT the correct answer.)

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
