Question

Through what potential difference must an electron pass to have a wavelength of 500A°?
(1) 6x 10^14 volt (2) 6x 10^-4 volt (3) 6 x 10^-9 volt (4) 6 x 10^9 volt​

Answer 1

Answer:

6×10^-4 volt

Explanation:

for electron, wave length =12.27÷square root of volt

by putting that value

we get v=6×10^-4volt
