Title: What is the irradiance (intensity, in W/m^2) of light transmitted through a thin piece of glass? Post by: trm76 on Jan 21, 2014 Sunlight is incident on an air-glass interface at angle of incidence theta, which is known. The irradiance (energy flux rate, W/m^2) of the incident light is known. The light must pass the interface from air to glass and then from glass to air. The indices of refraction are known. The angle of refraction is found easily from Snell's Law. In terms of these variables (or any I've forgotten), what is the irradiance of transmitted light?

Title: What is the irradiance (intensity, in W/m^2) of light transmitted through a thin piece of glass? Post by: zulukudzu on Jan 21, 2014 This problem, if you solve it correctly, is quite complicated, as said before. Some will be reflected, depending on angle of incidence. Some will be absorbed. There will be a frequency dependence on the transmission, depending on the materials involved.
