The kinetic energy of a subatomic particle is 5.85x10^-25 J. Calculate the frequency of the particular wave.
We know that KE = ½ mv^2
2KE = mv *v ,
we know that mv = h/ as per de Broglie’s equation ( =h/mv) then substituting the value we get,
2KE = h/*v
we know that v = v, substituting the value we get,
2KE = h/*v
2KE = h v
v = 2KE/h
v = 2(5.85x10^-25 J)/6.626x10^-34
v = 1.77x10^9 s^-1
