Answer 1

Hey that was a good question

First Consider the formula of De Broglie wavelength =h/Mv

and KE=1/2Mv^2

let, E = 1/2mv^2

v^2 = 2 E/m

v = √2 E/m

how using the above equation

wavelength = h/m√2E/m

= h/ √2mE

this is your answer, sorry for not using the formula bar since I am

not good using the android app.
