An alpha particle of energy 5.78 MeV is emitted from a particular nucleus.
Calculate the de Broglie wavelength of the alpha particle. How does it compare
with the nuclear diameter, which is known to be approximately 2x10−14 m.
E=h/p and E=hf
The Attempt at a Solution
I was thinking of using E=hc/lamda but this would be wrong because alpha particles don't travel at c.
