Standing electromagnetic waves
Webb12 juli 2024 · I've started reading Schwartz' Quantum Field Theory and the Standard Model, and the very first equation seems to have an extra factor of 2, yet I have a hard time believing the first equation of a popular textbook would be wrong after many printings. On page 1, Schwartz writes: A blackbody is an object at fixed temperature whose internal … WebbThe different types of electromagnetic waves are given in the section below-. Gamma rays – The frequency range of gamma rays is >3×10^17 Hz and wavelength range is <1nm. X rays – The frequency range of X rays is 3×10^16-3×10^17 and the wavelength ranges from 1 to 10 nm. Ultraviolet rays – The frequency range of ultraviolet rays is 7.5 ...
