Intensity and frequency formula
WebMay 17, 2024 · One formula for light intensity is I = n f h A t, where: n is the number of photons; h is Planck's constant; f is the frequency; A is the incident area; t is time. Another formula describes intensity as a function of the magnitude of electric field squared: I ( t) ∝ E ( t) 2 I = S = E 2 Z 0 How do I reconcile these two formulas?

WebA commonly used unit for frequency is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the motion of its nearest neighbor. WebMar 3, 2024 · The value of Planck’s constant is defined as 6.62607015 × 10 −34 joule∙second. For a blackbody at temperatures up to several hundred degrees, the majority of the radiation is in the infrared radiation region of the electromagnetic spectrum. At higher temperatures, the total radiated energy increases, and the intensity peak of the emitted ...
