Gamma, X-ray, UV, Visible, IR, Microwave, Radiowave
True or False: All electromagnetic radiation travels at the same velocity, the speed of light
True, 3*10^8 m/s
What does this calculate:
E= -2.18*10^-18(1/n^2)
Energy in a particular orbit
What does this calculate:
E=-2.18*10^-18(1/nf^2- 1/ni^2)
Energy absorbed or emitted to reach a certain orbit
