List of top Physics Questions on de broglie hypothesis asked in CUET (UG)

A proton accelerated through a potential difference of V volts has a de-Broglie wavelength \(\lambda\) associated with it. In order to get the same wavelength associated with an \(\alpha\)-particle, the required accelerating potential is

The de-Broglie wavelength associated with a ball of mass 150 g traveling at 30.0 m/s would be

A proton, a deuteron, an electron, and an \(\alpha\)-particle have the same energy. Their deBroglie wavelengths are \( \lambda_p \), \( \lambda_d \), \( \lambda_e \), and \( \lambda_{\alpha} \), respectively. Which of the following is correct?

An electron, an ɑ particle, a Proton and a deuteron have the same kinetic energy. which of these particles has the shortest de Broglie wavelength?
