Asked by Tiffie

Calculate the frequency of an electron traveling at 1.85X10^7 m/s.
Answered by DrBob222
wavelength = h/mv, then
c = wavelength*frequncy
Answered by Nicole
would the formula look like this?

v=(6.626x10^-340/9.11X10^-31x1.85x^7
would the answer then be 2.0X^-10

I did a quickie. I didn't get that.
wavelength = w
frequency = f

w = h/mv and
c = f*w
Then from c = f*w we get w = c/f
c/f = h/mv
cmv = hf
f = cmv/h
f = 3E8*9.11E-31*1.85E7/6.626E-34 = ?
