Picture a toddler. The child knows what the family cat looks like (provided they have one) but has no idea that there are a lot of other cats in the world that are all different. The thing is, if the kid sees another cat, he or she will still be able to recognize it as a cat through a set of features such as two ears, four legs, a tail, fur, whiskers, etc.

Problem Statement:
A one-dimensional string of length 2 meters is fixed at both ends, at position 0 and position 2 meters. The string has a linear mass density of 0.01 kilograms per meter and is under a tension of 100 newtons. Two harmonic wave sources are applied simultaneously:
Source 1: A wave generated at position 0, described by a displacement function with amplitude 0.02 meters, wavenumber 10 times pi radians per meter, and angular frequency 100 times pi radians per second, with a negative time term indicating rightward travel.
Source 2: A wave generated at position 2 meters, traveling in the opposite direction, with amplitude 0.03 meters, wavenumber 15 times pi radians per meter, angular frequency 150 times pi radians per second, and a phase shift of pi over 4 radians.
The wave speed on the string is determined by the square root of tension divided by mass density. Assume the waves combine without damping, and the boundary conditions, where displacement is zero at both ends, influence the wave behavior over time.
Question:
What is the total displacement of the string at position 1 meter and time 0.01 seconds, using the principle of superposition?
0.015 meters
0.038 meters
0.007 meters
-0.012 meters
Im ruhigen Dorf Harmonia, eingebettet an einem schimmernden See, versammelten sich die Dorfbewohner jeden Abend, um dem Tanz des Wassers zuzuschauen. Der See war etwas Besonderes: Seine Oberfläche kräuselte sich in den Wellen zweier uralter Quellen an gegenüberliegenden Enden. Eine Quelle, genannt Morgenhauch, sandte sanfte Wellen in gleichmäßigem Rhythmus, die leise wie ein Schlaflied plätscherten. Die andere, Abendpuls, trieb stärkere, schnellere Wellen, die mit einem temperamentvollen Takt ankamen, als würden sie mit der untergehenden Sonne um die Wette laufen.
Jeden Abend stand die junge Lila am mittleren Ufer des Sees und staunte darüber, wie die Wellen aufeinandertrafen. Wo Morgenhauch und Abendpuls sich überschnitten, prallten die Wasser nicht aufeinander, sondern verwoben sich, stiegen in anmutigen Wellenbergen auf oder sanken in ruhigen Wellentälern ab. Es war, als wäre der See lebendig und erzählte Geschichten durch seine sich ständig verändernden Muster.
Eines Abends bemerkte Lila etwas Neues. Die Stimmen der Dorfbewohner, die über das Wasser getragen wurden, schienen mit den Wellen zu verschmelzen. Ihr Lachen und Flüstern verschmolz mit der Bewegung des Sees und schuf eine Symphonie, die größer schien als die Summe ihrer Teile. Lila lächelte, als ihr klar wurde, dass der See ihr etwas Tiefgründiges darüber beibrachte, wie sich aus allem Schönes erschaffen lässt.
