an electron and proton have same kinetic energy which of the two has greater wavelength

Answers

Answered by aryangupta78901

I think both have equal wavelength..

namita2690: thnx aryan for answering.. but electron will have longer wavelength... the problem is i m not getting the reason why it is so..??

Answered by prabin100

wavelength of a particle is inversely proportional to its momentum p = m v; since a proton is about 1800 times more massive than an electron, its momentum at the same speed is 1800 times that of an electron, and therefore itswavelength 1800 times smaller.

The electron has the longer wavelength.

mark as brainliest please

namita2690: i've seen this answer on google but, i didn't understand
