To develop this problem we will use the concepts related to Speed in a string that is governed by Tension (T) and linear density (µ)
Our values are given as:
Replacing we have that the velocity is
From the theory of wave propagation the average power wave is given as
Where,
A = Amplitude
Angular velocity
Replacing,
Therefore the amplitude of the wave should be 0.0165m
The de Broglie wavelength m
We know that
de Broglie wavelength =
m
According to the de Broglie equation, matter can behave like waves, much like how light and radiation do, which are both waves and particles. A beam of electrons can be diffracted just like a beam of light, according to the equation. The de Broglie equation essentially clarifies the notion of matter having a wavelength.
Therefore, whether a particle is tiny or macroscopic, it will have a wavelength when examined.
The wave nature of matter can be seen or observed in the case of macroscopic objects.
