Suppose an electron and a proton move at the same speed. which particle has a longer de broglie wavelength? suppose an electron and a proton move at the same speed. which particle has a longer de broglie wavelength? the proton has the longer de broglie wavelength. since both are particles, it is meaningless to discuss a wavelength associated with them. both have the same de broglie wavelength. the electron has the longer de broglie wavelength.

Respuesta :

When both particles, the electron and the proton move at the same speed, they may have differences with their de Broglie wavelength, the particle that would have a longer wavelength would be the proton since the wavelength is in direct proportionality with the mass of the particle.
