How are photons measured/calculated

WebErnest Zinck. 7 years ago. The Balmer-Rydberg equation or, more simply, the Rydberg equation is the equation used in the video. 1/λ = R (1/i² -1/j²) It is usually written as. 1/λ = R (1/n₁² -1/n₂²), where n₁ < n₂. For the Balmer series of lines ( the visible lines in the hydrogen spectrum), n₁ = 2. WebT h e superficial conclusion would be that if the visible irradiance is about 50 per cent of that in the open, then a supplement of infra-red increases the weights of the seedlings, the increase being proportional to the intensity of the added infra-red. (Note that the irradiation is measured as the heat content, not as the flux of photons.)
