i have this question,
it says to calculate the wavelength of an electron travelling at 5.00x10^5 m/s. I dont know if its really simple or not but i cant find any equation to work it out. Please help
I think you need to use E=hf, rearrange it to get f=E/h. Find E (use information in the question), then find f, finally you can use the wave equation v=fλ to find wavelength. Hope that helps.
