Suppose you like to listen to two different radio stations. the opera station broadcasts at 90.5 mhz and the rock and roll station broadcasts at 107.0 mh. s. which station's signal has waves with longer wavelenghts and which stations signal has station has waves with higher energy?

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
