2. Calculate the de Broglie wavelength of an electron moving at 1/137th the speed

of light. (At this speed, the relativistic correction to the mass is negligible​

Explanation:

speed of light is 3×10^8 m/ s

1/137 of 3 × 10^ 8 m/s ( u get the speed the electron was moving with)

mass of electron 9.109× 10^-31 kg( i think we consider the mass of electron if the relativistic correction of the mass is negligible)

then from de Broglie wavelength= h/ mv

h is planck constant 6.626 × 10^-34

substitute the valies and you get the answer

am sorry I don't have my calculator with me I wuld hv written the answer bt I hope this helps
