Can anybody can help me with this one (modern / quantum physics)

1. Observations of alpha-decay show that different isotopes of the same element
(same # of protons, different # of neutrons) emit alpha particles with differing
amounts of kinetic energy. The reason the alpha particles have different amounts
of energy is because of ………

E=hv. v is the wavelength and that differs with each type of particle: alpha, beta, gamma.

alpha particles are more massive and larger than the rest. so they cant penetrate as far. yes.

you dont understand the questions. an alpha particle emitted by one isotope of the same atom can have different KE than an aplpha particle emitted by a different isotope of the same atom

for people who are in modern (post classical / newtonian) quantum .

I do not understand quantum physics yet, still waiting for the lightbulb to click on

M = distance object over distance image. That's what I learned today.
