Observe the following graph for the de-Broglie wavelength of a hypothetical charged particle $(q = 1.6 \times 10^{-19} \ C)$. Find the mass of the particle $(h = 6.0 \times 10^{-34} \ J \cdot s)$.

The de-Broglie wavelength of a particle with mass $1 \, g$ and velocity $100 \, m/sec$ is

According to the wave-particle duality of matter by de-Broglie,which of the following graph plots presents the most appropriate relationship between the wavelength of an electron $(\lambda)$ and the momentum of an electron $(p)$?

The wavelength (in $m$) of a particle of mass $1.67 \times 10^{-27} \ kg$ moving with velocity of $3.97 \times 10^6 \ m \ s^{-1}$ is:

In a hydrogen atom,the de Broglie wavelength of an electron in the second Bohr orbit is: [Given that Bohr radius,$a_0 = 52.9 \; pm$]

$A$ proton and a $Li^{3+}$ nucleus are accelerated by the same potential. If $\lambda_{Li}$ and $\lambda_{P}$ denote the de Broglie wavelengths of $Li^{3+}$ and proton respectively,then the value of $\frac{\lambda_{Li}}{\lambda_{P}}$ is $x \times 10^{-1}$. The value of $x$ is ............
(Rounded off to the nearest integer)
(Mass of $Li^{3+} = 8.3 \times \text{mass of proton}$)
