List of top Physics Questions on de broglie hypothesis asked in EAMCET

A proton when accelerated through a potential difference of $V$, has a de-Broglie wavelength $\lambda$ associated with it. If an $\alpha$ -particle is to have the same de-Broglie wavelength $\lambda$, it must be accelerated through a potential difference of

The de-Broglie wavelength of an electron moving with a velocity of $1.5 \times 10^{8} m / s$ is equal to that of a photon. The ratio of kinetic energy of the electron to that of the photon $\left(c=3 \times 10^{8} m / s \right)$
