## Question:

A wave on a string is described by the relation y = A sin(76t - 0.048x), where t is measured in seconds and x in meters, with A =0.19 m. What is the maximum speed of a point on the string?

## Particle Velocity:

The particle velocity when a wave passes through it is the rate of change of displacement of the particle. By differentiating the displacement function of a particle, we can get its velocity function. If the displacement function is a harmonic function, its velocity function will also be a harmonic function.

We have the following given data

\begin{align} \\ y& = A \sin(76t - 0.048x)\\[0.3cm] A &=0.19 ~\rm{m }\\[0.3cm] v_p^{max}& =\, ?...

Wave-particle duality means that light and sub-atomic particles can also behave as waves, hence the duality. Study the definition of wave-particle duality, the Davisson-Germer Experiment, the de Broglie wavelength, and an example calculation.
