Chapter 5 - Electromagnetic Radiation and the Bohr Model

electromagnetic radiation

energy transmitted by waves with electric and magnetic components

wavelength’s relationship with energy

shorter wavelengths have more energy and vice versa

wave

periodic movement that can transport energy

wavelength

distance between crests or troughs

frequency (Hz)

number of cycles per unit of time

stationary/standing waves

waves that do not move in space

quantization

only discrete values from a set of numbers are observed

nodes

1+ points that are not in motion between the end points

photon

particle of light

emission spectra/emission line

light emitted by a gas that has a set of discrete energies, every atom’s is unique

why don’t electrons constantly emit energy?

electrons would crash into the nucleus if they constantly emitted energy

when do electrons emit energy?

when jumping between energy levels

ionization energy

minimum amount of energy needed to remove an electron from an atom
