CHM 113 Lecture Notes - Electromagnetic Spectrum
Document Summary
Electromagnetic (em) radiation: form of energy that exhibits particle and wave-like behavior as it travels through space. Characterized by: wavelength ( ): distance between repeating points on a wave. Unit: nm (1nm = 1 x 10-9m: frequency ( or f): number of waves passed each second. Unit: hertz: hz: 1 hz = 1sec-1 = 1/sec: , and e are related by, e = h , e = hc/ , c = . E: energy, : wavelength, : frequency, h: plank"s constant (6. 63 x 10-34- j*s), c: speed of light (3. 00x 108 m/s) Conceptual relationships: e is directly proportional to , e is inversely proportional to , is inversely proportional to .
