Question

Calculate the ratio between the wavelength of electron and a proton if the proton is moving with half the velocity of electron

Answer 1

Calculate the de-Broglie wavelength of a helium atom at 27°C moving with a velocity of 2.40 x 102 ms"1 (atomic mass of helium atom = 4 a.m.u.) [Ans. 0.416 mm] 13. Calculate the ratio between the wavelength of an electron and a proton if the proton is moving with half the velocity of theelectrons 

Answer 2

The main concept in this question is–– l=h/mv

Where l is wavelength

h is planks constant

m is mass of particle

v is velocity of particle
