Answer:
The state of being free from the effects of gravity.
An atom in normal conditions refers when electrons are in the fundamental state. When you leave the atom, an electron absorbs energy from an external source and moves to a higher energy state.
Energy states or energy levels are called orbitals. The difference between the energy states in an atom is responsible for the emission of photons when an electron transition occurs between these two energy states.
Because the energy levels are discrete, the emitted photons also possess different energies.
Lifting weights, did this yesterday :))
Answer:
Mirages happen when the ground is very hot and the air is cool. The hot ground will have a warm layer of air just above it. when the light moves through the cold air and into the layer of hot air it is refracts (bent).
