To measure the response of your material you need to more clearly define what your input (excitation), and your output signals are going to be. If you decide your input is voltage then your choices for the output are probably limited to either current or displacement. Frequency is neither an input nor an output, but rather a property of the signals being ...

I agree with Wolfram jonny that you are wrongly assuming the pendulums collide. Instead they swing in a plane perpendicular to the plane of the paper, so they never touch - see the video in the link below. The apparatus is called "Barton's Pendulums" and is designed to illustrate Resonance. The oscillation of pendulum P causes a periodic driving force ...

Resonance is the process of driving a system to oscillate at a resonant frequency. The property of these frequencies is that they can store vibrational energy or vibrational quanta depending on the description you choose. This means that driving the system at these frequencies can create much larger amplitude oscillations than other frequencies, which ...

Resonance is the name for the phenomenon. The resonant frequency is the frequency at which this phenomenon occurs. The frequency of the oscillation when you observe resonance. Frequency is just one of the characteristics of a resonance. Another one is Q factor. Others might be the mode structure of the resonant wave.

This is like a driven harmonic oscillator problem where driver is the tuning fork. If the sound box have same frequency as of tuning fork the energy stored in tuning fork will quickly transfer into sound box, then it will dampen subsequently and that is the reason for faster damping. On the other hand if you provide energy to sound box then the sound box ...

The answer has pretty much been given in the comments, but I think a nice pictorial representation might help. The mathematical form of a standing wave is $$y(x) = \sin \left(\frac{2 \pi}{ \lambda} x \right) $$ Here $y(x)$ is the displacement of the string at point $x$. If we plot the waves for the four wavelengths we obtain the following picture I will ...
