Ig the energy is equal to h*v/lambda thing is incorrect.
It would be h/mv=lambda_p and then (mv^2/2):hc/(h/mv)=v:2c=c/4:2c=1:8
can u explain why
I don't think kinetic energy of electron can be given by h nu
That's something called Compton frequency etc.
Ke is always 1/2 mv2 (for non zero mass things lol]
OMG I CANT READ I SOLVED IT THINKING IT READ PROTON
BRUH
i think you wrote the expression for energy wrong shouldnt it be like K.E electron= h^2/2lambda^2 Me
and photon energy is just hc/lambda
For massive (having mass) bodies, kinetic energy is p²/2m
For non massive bodies, ie, quanta/photons, it's pc = h(nu)
