optics - Light intensity through polarizers and a diffuse ...

1 Answer1. Active Oldest Votes. 1. The directly reflected light retains its polarisation so can be blocked by choosing θ = 90 o. The diffused light is unpolarised so half of it is lost in the second polariser. Of course, if your light source is unpolarised to begin with, you also lose half of the overall intensity in the first polariser. Share.

What is Light Intensity? - California Lightworks Grow Lights

Oct 16, 2019 · Red and blue light appear quite dim to human eyes, but for plants, red and blue are the most photosynthetically active wavelengths on the light spectrum. Therefore, if you confuse “intensity” with “brightness,” your perception will cause you to favor lights that look powerful to you over lights that are powerful for your plants.

Luminous intensity - Wikipedia

In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye.The SI unit of luminous intensity is the candela (cd), an SI base unit.. Photometry deals with the measurement of visible light as perceived by human eyes.

size effect has a larger influence on light than heavy elements. Moreover, it is recommended that the grain size for a set of samples is the same. If pulverization condition differs, the analysis result can be different even for the same sample. This is because the X-ray intensity can vary depending on grain size distribution after pulverization.
