Orbital

What is the difference between orbital and reiprocating when it comes to sawzall type saws?
Q. I noticed that orbital costs more, just wondering if there is any major differences in functionality, or just durability. I wont use it often, but want it to function well. Thanks!

A. A reciprocating saw has a motion like an automated hand saw like your grandpa used to use before there were circular saws. It's very handy for sawing in places where a circular saw will not reach. I have a reciprocating saw and use it every now and then. I think it's mostly useful in construction (cutting out a header). You can insert a metal blade and cut through metal pipe. I've never owned an orbital saw. I think it's useful in furniture making, crafts, and in small construction jobs (cutting a hole in sheetrock).

why does an electron return to its orbital after being excited by a photon?
Q. When a photon excites an atom, it moves to an orbital of higher energy. What brings the electron back into its orbital?

A. Once it looses its energy after being excited it returns to its orbital position due to the forces acting on it in the atom. Much like gravity: once it used up the energy it obtained it the forces pull it towards its original orbital position.

A. The nature of the angular momentum imparted to the electron. S orbitals have less angular momentum than P orbitals.
