Noob question ahead. So basically I'm reading about atoms and photons in my textbook at the moment and I came across excitation and why atoms emit photos with certain wavelengths when hit by white light. The claptrap doesn't really matter, what I'm confused and curious about is how many times does an atom "excite" every second when light shines onto it. I've understood that when photos hit an atom, i.e. hydrogen the electrons around the nucleus gets excited and jumps up one energy level(orbital), and when they "fall" down again, the difference in energy is what gets emitted as a photon. This is the part that I am curious about. If a 1000 photos hit an atom a second does that basically mean that the single atom gets excited 1000 times and emits 1000 photos with the wavelength that accompanies that change in energy. Please help, thank you.
