Physics Question from JEE Main 2025 · 28 January, Shift 1

A proton of mass mpm_p has the same energy EE as that of a photon of wavelength λ\lambda. If the proton is moving at non-relativistic speed, then the ratio of its de Broglie wavelength to the wavelength of the photon is:

  • A

    1cE2mp\frac{1}{c}\sqrt{\frac{E}{2m_p}}

  • B

    1cEmp\frac{1}{c}\sqrt{\frac{E}{m_p}}

  • C

    12cEmp\frac{1}{2c}\sqrt{\frac{E}{m_p}}

  • D

    1c2Emp\frac{1}{c}\sqrt{\frac{2E}{m_p}}
